Question

The angle of incident ray and reflection ray is 60 what is a value of incident ray

Answer 1

Incident Ray and reflected Ray angle = 60°

Angle of incidence = 60°/2 = 30°

Answer 2

Let us take the angle of incidence as i and angle of reflection as r.

According to question

I + R = 60

Laws says that - i = r

i + i = 60

2i = 60

i = 60/2

i = 30
