Given :-
A ray of light makes an angle of 50° with surface s₁ of the slab
To Find :-
Angle of incidence
Solution :-
According to the question
Angle of ray + Angle of incidence = Angle of a right angle
∠r + ∠i = 90
Given,
Angle of ray is 50°
So, We need to find the angle of incidence
Let the angle of incidence be ∠i
50 + ∠i = 90
∠i = 90 - 50
∠i = 40
Hence
Angle of incidence is 40°
