Question

if the angle between the normal and the incident ray is 30* the angle between the incident and the reflected ray will be

Answer 1

It will be of 30° only

Answer 2

Angle between Incident ray and Normal = 30°=∠i

As we know,  ∠i = ∠r 

⇒ ∠r = 30°

∠i + ∠r = 60° (Angle between incident ray and reflected ray)

Answer = 60°
