Question

Consider a spherical wavefront incident on a plane mirror. After reflection, we will get,

• A. a plane wavefront
• B. Insufficient information
• C. a cylindrical wavefront
• D. a spherical wavefront

Answer 1

The correct option is D a spherical wavefront

As a result of reflection, there is no change in shape of the wavefront. i.e. a spherical wavefront is reflected as a spherical wavefront.

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