Question

What is the angle of reflection at the point of incidence?
(1) 90°
(2) 45°
(4) 60°
(3) 30°​

Answer 1

Explanation:

Take triangle AOC,

OAC = 45°

ACO = 90°

x = ?

We know sum of all angles of triangle is = 180°

x = 180-(45+90)

x = 180-135

x = 45°

Angle of incidence = 45°

Angle of reflection = 45°
