Question

A
ray of light falls on a plane mirror
angle of 45° Through what
angle is it turned on reflection ?​

Answer 1

Answer:

45°

Step-by-step explanation:

Angle of incidence = Angle of Reflection (Mirror Law)

Angle i = Angle r

Angle of incidence with the plane given = 45°

Angle of incidence = 90°-45°

Angle of reflection = 45°

Also angle of reflection with the plane will be 45°
