Question

2. If the angle between the incident ray and a plane mirror is 30°, then what will be the angle
of reflection?
​

Answer 1

Answer:

Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.

Answer 2

Explanation:

Angle between incident ray and plane mirror=30

Normal is a perpendicular i. e. 90

Angle of incidence=normal-angle between incident ray and plane mirror

this implies:Angle of incidence=90-30= 60

since, angle of incidence= angle of reflection

so, angle of reflection= 60
