Question

The angle between the incident ray and reflected ray is 90°. Calculate the angle of incidence and the angle of reflection.​

Answer 1

Explanation:

The angle of incidence and reflection is 45°

The angle between them is 90°

they lie on the same plane, and angle of incidence = angle of reflection

the sum of all the angles is 180°

let angle of incidence and reflection be x

therefore,

90 + 2x = 180

x = 45°
