Question

Spherical wavefronts shown in the figure, are incident on a plane mirror. The reflected wavefront will be, as shown in,

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Let $O$ is a point source of light from which the spherical wavefronts originate, then, its image $I$ will also act like source, emitting spherical wavefronts as shown.

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

$\begin{array}{c}\text{Why this question?}\\ \text{To understand how wavefront will solve when it will be incident on a plane mirror.}\end{array}$
