Question

The direction of a 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 $1,2,3and4$.
Which of the four rays correctly shows the direction of reflected ray ?

• A. $4$
• B. $3$
• C. $2$
• D. $1$

Answer 1

The correct option is C $2$

In a spherical mirror, when a beam of light passing through Focus falls on the mirror, the ray after reflection from the mirror becomes parallel to the principal axis of the mirror.

The ray number $\left(2\right)$ travels parallel to the principal axis after being reflected and remains on the same side of the incident ray. The ray number $\left(4\right)$ is not possible because the ray cannot travel on the opposite side of the mirror after reflection.

Hence, option $\left(C\right)$ is correct.
