Question

a ray of light fall on a mirror.it is observed that incident ray is perpenducular to reflected ray. calculate the angle between the mirror and incident ray

Answer 1

Answer:

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle of incidence . Both angles are measured with respect to the normal to the mirror.

i. Angle of incidence = 90° - Angle between incident ray and mirror = 90 - 45 = 50°

ii. Angle of reflection = Angle of incidence = 50°

iii. Total angle turned = Angle of incidence + Angle of reflection.
