CBSE NCERT Solutions For Class 8 Science Chapter 16 – Light: Chapter Summary

The world can be seen thanks to our eyes. Human beings have five basic senses: sight, hearing, smell, taste, and touch. Sight is possible because of the function that our eye performs. Let’s see in this chapter how we are able to see, why there are different colors, and why we cannot see some things although it exists. In order to understand this, you have to understand why we can see objects. We can only see when the light enters our eyes.

Every object that you are seeing right now is emitting or reflecting some amount of light. Our eyes are sensitive enough to feel these things. That’s why in dark you cannot see things because there are no light rays falling on the object and making the things appear. A mirror or a shiny surface can change the direction of light because it emits most of the light falling in it. When a light ray falls on the mirror, it is called an incident ray. After the light ray has been emitted, it is called a reflected ray. If you conduct an experiment where you have kept one mirror and made a light ray to pass through it, then you will notice that the angle of the incident ray is always equal to the angle of the reflected ray. This is known as the law of reflection.

Here we have provided some of the frequently asked questions related to this chapter:

Q1: Mention against each of the following whether regular or diffused reflection will take place when a beam of light strikes. Justify your answer in each case.
(a) Polished wooden table
(b) Chalk powder
(c) Cardboard surface
(d) Marble floor with water spread over it
(e) Mirror
(f) Piece of paper

A: a) The wooden table that has been a polished – Regular reflection.
The surface that has been recently polished can be a good example of a smooth surface. The wooden table that has been polished has a surface that is smooth.
b) White Chalk powder that is used in school – Diffused reflection. Chalk powder spread on a surface is an example of an irregular surface. Hence, it is rough. Therefore, the diffused reflection will appear from chalk powder.
c) Cardboard surface – Diffused reflection
The surface of the cardboard is a kind of irregular surface. Hence, the diffused reflection will take place from a cardboard surface.
d) Marble floor – Regular reflection
Marble floor can be a good example of a surface that is regular. Because water makes the ceramic glossy. Thus, the reflections that are regular occurs on this surface.
e) Mirror – Regular reflection
A mirror has a very smooth surface hence it gives a regular reflection.
f) Piece of paper – Diffused reflection
Although a piece of paper may look smooth, it has many irregularities on its surface. Because of this reason, it will give a diffused reflection.

Q2: State the laws of reflection.

A: The law of reflection states that
i) The angle of reflection and the angle of incidence both are always equal to one another.
ii) The reflected ray, the incident ray, and the normal to the reflective surface at the point of incidence all come on the same plane.

Q3: Fill in the blanks in the following.
(a) A person 1 m in front of a plane mirror seems to be _____ m away from his image.
(b) If you touch your _____ ear with right hand in front of a plane mirror it will be seen in the mirror that your right ear is touched with _____.
(c) The size of the pupil becomes _____ when you see in dim light.
(d) Night birds have _____ cones than rods in their eyes.

A: (a) A person 1 m in front of a plane mirror seems to be 2m away from his image.
(b) If you touch your left ear with right hand in front of a plane mirror it will be seen in the mirror that your right ear is touched with the left hand.
(c) The size of the pupil becomes large when you see in dim light.
(d) Night birds have fewer cones than rods in their eyes.

Q3: The angle of incidence is equal to the angle of reflection.
(a) Always
(b) Sometimes
(c) Under special conditions
(d) Never

A: The correct answer is (a) Always

Q4: Image formed by a plane mirror is
(a) virtual, behind the mirror and enlarged.
(b) virtual, behind the mirror and of the same size as the object.
(c) real at the surface of the mirror and enlarged.
(d) real, behind the mirror and of the same size as the object.

A: The correct answer is (b) virtual, behind the mirror and of the same size as the object.

Q5: Two mirrors meet at right angles. A ray of light is incident on one at an angle of 30° as shown in Fig. 16.19. Draw the reflected ray from the second mirror.

A: The first law of reflection is used to obtain the path of reflected light. It can be observed that the given ray of light will reflect from the second mirror at an angle of 60°.
