Question

what is the angle between incident and reflected rays when a ray of light is incident normally on a plane mirror?​

Answer 1

Explanation:

The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Answer 2

The angle between incident and the reflected ray will be 0 degrees.

• The angle between the incident ray and the mirror is called angle of incidence while the angle between reflected ray and the normal is called angle of reflection.
• Here, the a ray of light is incident normally on a plane mirror. The reflected ray will trace back the incident ray due to the law of reflection.
• As a result, the angle between incident and the reflected ray will be 0 degrees.
