Question

The angle between the incident ray and reflected ray is 120 what is the (1) angle of incidence?
(2)angle of reflection?

Answer 1

Answer:

(1) 60

(2) 60

because incident angle = reflected angle

Answer 2

If I understood your question, then guess you want to ask the angle of Incidence for a ray of light on a plain reflecting surface, which is making an angle of 120° with the reflected light.

The answer is 30°.

Explanation: If we consider the surface is flat surface (ideal), then total angle is 180°. Then if the angle between the Incident Ray and Reflected Ray is 120° then we are left with (180° - 120°) = 60°. This 60° is equally divided between the Incident Ray and the Reflected to follow the Laws of Reflection. So, 60° / 2 = 30°.
