Question

The angle between incident ray and reflected ray is 60°. What is
the value of angle of incidence​

Answer 1

Since the normal bisects the angle between the incident ray and reflected ray.

So, angle between the incident ray and the normal is

i = 2÷60=30°

Answer 2

αηѕωєя ☆ﾟ.*･｡ﾟ

Angle of incidence is 30°. 30 degrees. This is because "the angle between incident ray and reflected ray" actually means, angle of incidence+angle of reflection. Since angle of incidence=angle of reflection,angle of incidence =(60/2)=39
