The angle of incidence at the first mirror will this ray strike the midpoint of the second mirror is 34.6°
Two plane mirrors intersect at right angles. A laser beam strikes the first of them at a point d = 10.0cm from their point of intersection.
To strike the midpoint of the second mirror, the ray of light will have to travel half of the distance vertically
i.e. 29/2 = 14.5
We can solve this through trigonometry.
Let the angle between the ray and the vertical plane mirror is known as α
tan α = 10/14.5
α = = 34.6°
The angle of incidence is the angle between the ray and the normal line of the mirror.
Let the angle of incidence of the first mirror be β
β = α = 34.6
