Question

show that plane mirror makes regular reflection​

Answer 1

Answer:

Place a strip of plane mirror in the path of the light ray . After striking the mirror, the ray of light is reflected in another direction. ... This line is known as the normal to the reflecting surface at that point . The angle between the normal and incident ray is called the angle of incidence (∠i).

Answer 2

Explanation:

Thus, a plane mirror produces regular reflection of light. Since the angle of incidence and the angle of reflection are the same or equal, a beam of parallel rays falling on a smooth surface is reflected as a beam of parallel light rays in one direction only.
