Question

A light ray strikes a reflective plane surface at an angle of 31 degree with the surface
(a) calculate the angle of incidence
(b) calculate the angle of reflection
(c) calculate the angle made by reflected ray and the surface
(d) calculate the angle made by incident ray and reflected ray​

Answer 1

Answer:

the answer is option d

by calculating the angles of incident and reflecting rays

Answer 2

Answer:

Note(a)= angle of incidence is the angle between the incident ray and normal.

Note(b) = angle of incidence = angle of reflection

Explanation:

a) Angle of incidence = 31°

b) Angle of reflection = 31°
