If she measures the angle between the mirror and an incident ray and finds that it is 30°, then the angle of the incidence would be 60° and the angle of the reflection would be 60° as well because of the laws of the reflection.
The law of reflection states that when a ray of light reflects back from a surface the angle of incidence of light on a surface is equal to the angle of reflection.
As given in the problem statement A student does an experiment with a mirror. She measures the angle between the mirror and an incident ray and finds that it is 30°.
the angle of incidence = 90° - 30°
=60°
As per the laws of the reflection
the angle of the incidence = angle of reflection
the angle of the reflection = 60°
Thus, the angle of the incidence would be 60° and the angle of the reflection would be 60° as well.
