The direction of ray of light incident on a concave mirror is shown by `PQ` while directions in which the ray would travel after reflection is shown by four rays marked `1,2,3` and `4`, Fig. Which of the four rays correctly shows the direction of reflected ray ?
.

A

`1`

B

`2`

C

`3`

D

`4`

Text Solution

Verified by Experts

The correct Answer is:
B
In Fig. `PQ` is a ray of light passing through focus, and falling on the surface of a concave mirror. On reflection, from the mirror, the ray becomes parallel to principal axis of the mirror. Choice (b) is correct.
