Class 6 Science Chapter 8 Case Based Questions - Light, Shadow and Reflections

Sarah is conducting an experiment with different objects to understand the properties of light. She has a wooden box, a glass pane, and a candle. She is using a source of light to observe the behavior of these objects.

Q1: What type of object is the wooden box in this scenario, and why? Ans: The wooden box is an opaque object because it does not allow light to pass through it. Q2: If Sarah observes that she can see through the glass pane clearly, what type of object is it, and why? Ans: The glass pane is a transparent object because it allows light to pass through it clearly. Q3: How does the behavior of the candle differ from the wooden box and the glass pane in terms of emitting light? Ans:   The candle is a luminous object because it emits its own light. Q4: Which of the following objects is an example of a translucent object? (a)  Wooden box (b)  Glass pane (c) Candle Ans:   (b) Q5: What is the primary characteristic that distinguishes a luminous object from a non-luminous object?

Access Class 6 Science Chapter 11 – Light, Shadows and Reflection Notes

Definition of light.

Light is a form of invisible energy, perceived by eyes when scattered by small dust particles that stimulate sight and makes things visible. 

Due to the scattering of light, other objects are visible. 

Light and the eyes both are necessary to see things. 

The sensation caused by light that helps us to see things is called sight or vision.

Sources of Light

Natural: sources that have their own energy to create light.

For example Sun, stars, candle flames etc. 

Artificial: The man-made sources of light are called artificial sources of light. 

For example light bulbs, tube lights, torch etc.

Classification of Light: On the Basis of Its Emission.

Luminous Objects: Objects which emit light of their own are called luminous objects.

For example sun, torch, candle flame. 

Non-Luminous Objects: Objects which do not have the light of their own and are visible due to reflection or scattering of light are called non-luminous objects.

Example: moon, rainbow, table etc. 

Optical media and its types

Optical Media: Any substance through which light travels is called optical media.

Transparent Object: a substance through which light passes without any obstruction is called a transparent object. Objects seen through them are clearly visible. For example glass, water, air etc.

Translucent Object: a substance that obstructs some part of the light and the light cannot pass through them completely is called a translucent object.

          For example butter paper, etched glass etc. 

Opaque Object: a substance that does not allow light to pass through it is called an opaque object. 

For example wood, metal etc. 

Definition of Shadow

A shadow is the 'region of the absence of light' caused by an object which does not allow light to pass. As light travels in a straight line, the light obstructed by the object causes a dark region with no light.

A shadow is formed in the presence of a light source.

Opaque and translucent objects which restrict the light to pass through them form a shadow, transparent objects do not produce a shadow. 

Properties of a shadow

Due to Size of Light Source:

A. Due to the smaller (point) light source: Only one dark shadow is formed. This is known as the umbra. 

B. Due to larger(extended) light source: number of shadows formed are two, a dark one in the centre and a light one on the of the direction of propagation of light;

A dark shadow is called the umbra.

A faint or lighter shadow is called a penumbra.

The size of these shadows depends upon the positioning of the screen with respect to the object. The size of the umbra decreases and the penumbra increases as the screen is moved away from the object and vice-versa. 

Colour of Shadow:

The colour of the shadow is black due to the absence of light, irrespective of the colour of the object. 

Length of the Shadow:

The length of the shadow depends on the angle at which light is incident on an object. For example, the length of a person's shadow decreases as the sun rises overhead.

Eclipse: 

A shadow is formed in space which makes the sun or the moon invisible for some duration. Eclipse is the phenomenon of overshading a bright object with another object. 

Types of the Eclipse: 

Solar Eclipse: The moon comes between the sun and the earth during its revolution around the earth, which causes darkness on the earth (in the shadow) during the day.

Lunar Eclipse: The sun, moon and the earth are in a straight line such that the earth comes in between the sun and the moon and obstructs the light of the sun to reach the moon, that is, the shadow of the earth falls on the moon and the moon is not visible. 

Definition of Reflection of Light: 

The bouncing back of a light ray after striking an object at some angle is known as reflection. We see our image in a mirror after reflection. The objects around us are visible due to the reflection of light.

Light Shadows and Reflections Class 6 Notes Science Chapter 11

Introduction

Light is a form of energy which helps us in seeing objects. When light falls on an object, some of the light gets reflected. The reflected light comes to our eyes and we are able to see an object.

Sources of Light

Objects that produce their own light are called  Luminous Objects.  Example, Sun, Fire

Objects that do not produce their own light but are visible when reflect light falling on them are called  Non-Luminous Objects.  Example – Table, planets.

Rectilinear propagation of light

Light takes the quickest path between any two points. Therefore, light travels in a straight line. This is known as a rectilinear propagation of light.

Transparent, Opaque and Translucent Objects

Luminous & Non-luminous objects

• Objects that emit light and heat are known as luminous objects. E.g.: Sun and other stars
• Objects that do not produce their own light but reflect the light emitted by luminous objects are known as non-luminous objects. E.g.: Earth, trees

Objects can be classified based on their interaction with light.

• Transparent objects allow light to pass through them without getting scattered. E.g.: glass
• Translucent objects allow light to pass through them partially. E.g.: Butter paper
• Opaque objects do not allow any light to pass through them. E.g.: a table, a book, etc

Shadows  are dark regions formed when an opaque object blocks the path of light. This formation is possible only because light only travels in a straight line.

Shadow formation

• A shadow is formed when an opaque object comes in the path of light.
• A shadow needs a screen where it is formed, for example, the ground, or walls of a room or even the surfaces of buildings.
• Shadows give us an idea about the shapes of different objects. Or, it can even mislead us about the shape of different objects. E.g. the shadow of a cone appears to be a triangle on the screen.

The Pinhole Camera

Formation of image by pinhole camera

• A pinhole camera is a simple camera that consists of a light-proof box, a thin film for a screen and a small aperture or hole to allow the passage of light rays.
• The light from outside enters through the small hole and forms an image on the screen that is inverted.

How to make a Pinhole Camera?

Step 1:  Take two cardboard boxes one larger than the other such that one box slides into the other without any gap.

Step 2:  Cut out open one side of each box. On the opposite side of the larger box cut a small hole in the centre.

Step 3:  On the opposite side of the smaller box cut a square of about 5 cm and cover this open area with a tracing paper.

Step 4:  Slide the smaller box inside the larger one such that the side with the tracing paper is on the inside.

Step 5:  Cover the camera and your head with a black cloth and then get ready to observe the distant objects.

Natural Pin-hole Camera

When we pass under a tree covered with large number of leaves, we notice that small patches of sun light under it. These circular images are, in fact, pin hole images of the Sun. The gaps between the leaves, act as the pin holes. These gaps are all kinds of irregular shapes, but, we can see circular images of the Sun. This is called Natural Pin-Hole Camera

Mirrors and Reflection

A mirror is a surface usually consisting of a glass that reflects light incident on it to form clear erect images.

When light is incident on a surface, it gets reflected or it bounces back. Any surface that is really well polished or shiny acts like a mirror. The phenomenon of light bouncing off surfaces is called reflection.

Characteristics of images

• Images have colour, unlike shadows. They are formed due to the converging rays of light that comes after reflecting from objects.
• A real image is formed by actual convergence of light rays. Real images always form on a screen.
• A virtual image is the apparent convergence of diverging light rays. Virtual images cannot be obtained on a screen.

Plane mirrors and images formed by them

A plane mirror changes the direction of light that falls on it.

This enables us to see images. Take the example of a comb placed in front of a mirror over a dark coloured paper. Let a beam of light pass through the comb on the mirror using a torch. Then an image is observed similar to the one given:

We observe that the light gets reflected from this mirror and it travels in straight lines.

(c) Both the size and shape of the shadow of the tree change. (d) Neither the shape nor the size of the shadow changes. Solution:

(c): Both the size and shape of the shadow of the tree change.

The Sun being the source of light, changes its position at different points of time. So, accordingly, the size and shape of the shadow of the tree change.

6. Which of the following can never form a circular shadow? (a) A ball (b) A flat disc (c) A shoe box (d) An ice cream cone Solution:

(c): A shoe box

(c): Glass sheet

Only the glass sheet can reflect light properly in order to form their images.

Very Short Answer Questions:

8. You have 3 opaque strips with very small holes of different shapes, as shown in fig 11.5. If you obtain an image of the sun on a wall through these holes, will the image formed by these holes be the same or different?

All these three objects form the same images. These opaque strips will act as pinholes and image of the sun will be obtained on the wall.

9. Observe the picture given in fig 11.6. A sheet of some material is placed at position ‘P’, still the patch of light is obtained on the screen. What is the type of material of this sheet?

Light passes through only transparent material hence, sheet P must be of transparent material as it allows light to pass through it.

10. Three torches A, B and C, shown in fig 11.7 are switched on one by one. The light from which of the torches will not form a shadow of the ball on the screen.

We know that light travels in a straight line. The light from torch C will not form a shadow of the ball on the screen. Since torch C is placed parallel to the screen light cannot pass through the screen.

11. Look at the given figure.

Will there be any difference in the shadow formed on the screen in A and B? Solution:

No, shadows formed on screens A and B will be the same.

12. Correct the following statements. (i) The colour of the shadow of an object depends on the colour of the object. (ii) Transparent objects allow light to pass through them partially. Solution:

(i) No, the colour of the object does not depend on the colour of the shadow since the shadow is usually dark in colour.

(ii) Transparent objects allow most of the light to pass through them. Translucent objects allow light to pass through them partially.

13. Suggest a situation where we obtain more than one shadow of an object at a time. Solution:

At a time, we can obtain more than one shadow of an object if the light from more than one source falls on it.

For example: In a cricket stadium, we can observe multiple shadows of players since the light falls on them from different directions.

14. On a sunny day, does a bird or an aeroplane flying high in the sky cast its shadow on the ground? Under what circumstances can we see their shadow on the ground? Solution:

No, a bird or an aeroplane flying high in the sky cannot cast its shadow on the ground even on a sunny day because they are flying at a higher altitude where the object cannot obtain its shadow.

We can only see their shadow on the ground if they are flying very close to the ground.

15. You are given a transparent glass sheet. Suggest any two ways to make it translucent without breaking it. Solution:

A transparent glass sheet can be made into a translucent glass sheet without breaking it by:

(i) Applying oil, grease, butter on it or pasting a butter paper on it.

(ii) Rubbing the surface of the glass by any abrasive material like sandpaper on it.

16. A torch is placed at two different positions A and B, one by one, as shown in fig. 11.9.

The shape of the shadow obtained in two positions is shown in fig. 11.10.

Match the position of the torch and shape of the shadow of the ball. Solution:

Position A will form the shadow ‘a’.

Position B will form the shadow ‘b’.

As the position of torch changes, we can observe the change in the shape of the shadow.

17. A student covered a torch with red cellophane sheet to obtain red light. Using the red light, she obtains a shadow of an opaque object. She repeats this activity with green and blue light. Will the colour of the light affect the shadow? Explain. Solution:

No, the colour of light will not affect the shadow because the shadow is usually dark or black patch formed when an object obstructs the path of light and hence no light reaches in the shadow region.

18. Is the air around us always transparent? Discuss. Solution:

Yes, the air around us is transparent, which makes things visible to our eyes. When thick smoke/ thick clouds, etc. are present in the air it does not remain transparent it makes visibility difficult.

19. Three identical towels of red, blue and green colours are hanging on a clothes line in the sun. What would be the colour of shadows of these towels? Solution:

Shadow is usually dark or black in colour. Hence, the colour of shadows of all the three towels will remain same as no light passes through them.

20. Using a pinhole camera a student observes the image of two of his friends, standing in sunlight, wearing yellow and red shirt respectively. What will be the colours of the shirts in the image? Solution:

Pinhole camera does not change the colour of the image. The colours of the shirts in the image will remain the same as the colour of the shirt. But the image of the person will be inverted when seeing through a pinhole camera.

21. In fig 11.11, a flower made of thick coloured paper has been pasted on the transparent glass sheet. What will be the shape and colour of shadow seen on the screen?

The shadow formed will be of the shape of a flower along with the stalk and the shadow will be dark in colour.

Long Answer Questions:

22. A football match is being played at night in a stadium with floodlights ON. You can see the shadow of a football kept at the ground but cannot see its shadow when it is kicked high in the air. Explain. Solution:

We can see the shadow of football lying on the ground because the ground acts as a screen for it. However, when the football is kicked high into the air it will be away from the ground, the shadow disappears with height hence we cannot see the shadow of the football when it is in air.

23. A student had a ball, a screen and a torch in working condition. He tried to form a shadow of the ball on the screen by placing them in different positions. Sometimes the shadow was not obtained. Explain. Solution:

Some of the reasons why shadow was not obtained can be

(i) The screen is far away from the ball.

(ii) The beam of light from the torch is falling parallel to the screen on the ball.

(iii) The torch is kept away from the ball.

24. A sheet of plywood, a piece of muslin cloth and that of a transparent glass, all of the same size and shape were placed at A one by one in the arrangement shown in fig 11.12. Will the shadow be formed in each case? If yes, how will the shadow on the screen be different in each case? Give reasons for your answer.

Shadow will not be formed in any of the cases. Only the piece of muslin cloth and the sheet of plywood will cast a shadow on the screen.

(i) The piece of muslin cloth will form a lighter shadow as it allows light to pass through it partially.

(ii) The sheet of plywood will form a dark shadow as it blocks the path of light completely.

(iii) The transparent glass will allow most of the light to pass through it. So, no shadow will be obtained on the screen.
