CBSE-class 8- Science - Ch16 - Light - ncert book Solution

Q1. Suppose you are in a dark room. Can you see objects in the room? Can you see objects outside the room. Explain.

Answer: We can see any object, when light reflected by that object reaches our eyes. But in the dark room, no light is reflected by the object. Hence, we are unable to see the objects in dark room. But if there is light outside the room, we can see the objects lying there.

Q2. Differentiate between regular and diffused reflection. Does diffused reflection mean the failure of the laws of reflection?

Answer:
S.No. Regular reflection Diffused reflection
1. It takes place from a smooth or regular surface. It takes place from a rough surface.
2. All reflected rays are parallel to each other. The reflected rays are not parallel to each other.
3. Reflected rays go in one direction. Reflected rays are scattered in different directions.
4. e.g. it is caused by smooth surfaces such as mirror. e.g. It is caused by the irregularities in the reflecting surface, like that of a cardboard.
(Draw fig 16.8 and 16.7 from the book)

In diffused reflection, each ray obeys the laws of reflection. Therefore, laws of reflections are not violated. 

Q3: 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
