Question

2. A ray of incident on a surface makes a
30° angle with the surface. Calculate
the angle of incidence and the angle
of reflection?​

Answer 1

Answer:

The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). Angle of incidence = 90 - angle made with the mirror surface= 90 - 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees.

Answer 2

Explanation:

The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). Angle of incidence = 90 - angle made with the mirror surface= 90 - 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees.
