Question

Explain a mirror and ils Classication. What happens when the incident ray strikes the reflecting surface normally?​

Answer 1

Answer:

For a plane mirror: If the incident ray falls along the normal, the angle of incidence is 0 degrees, NOT 90 degrees. The angle is measured with the normal to the mirror and not with the plane of the mirror. Hence the angle of reflection is equal to 0 degrees.

Answer 2

Answer:

A mirror is a smooth surface on which regular reflection takes place. A clear image of an object placed in front of a mirror is formed due to reflection of light. Mirrors can be broadly classified as plane mirrors, rotating mirrors, inclined mirrors and spherical mirrors. Moreover, spherical mirrors can be further classified into two types, i.e. a concave spherical mirror and a convex spherical mirror.

For a plane mirror: If the incident ray falls along the normal, the angle of incidence is 0 degrees, NOT 90 degrees. The angle is measured with the normal to the mirror and not with the plane of the mirror. Hence the angle of reflection is equal to 0 degrees.
