Question

The angle between the incident ray and reflected ray is 100°. What is the value of angle of incidence?​

Answer 1

Answer:

Law of reflection states that when any ray is incident on a reflecting surface, the reflecting ray will reflect with the same angle. It means the angle of incidence is equal to the angle of reflection.

Angle of incidence is the angle made by incident ray with the normal.

Normal is a perpendicular line at the interface of two mediums.

Angle of reflection is the angle made by reflecting ray with the normal.

Since, angle between reflecting ray and incident ray is 100^{0}100

0

, and normal bisects this angle into equal parts, i.e. angle of incidence and angle of reflection.

Therefore, angle of incidence = angle of reflection = 50^{0}50

0
