Question

The
Angle between incident out and released
Say is 90°. then angle of incident is
​

Answer 1

Answer:

45°

Explanation:

as we know angle of incidence = angle of reflection

so,

let the angle of incidence be x

therefore,

angle of reflection will also be = x

given,

angle of incidence+angle of reflection = 90°

x+x = 90°

2x = 90°

x = 90/2

x = 45°
