Question

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

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

Answer 1

The correct option is B 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.
