Aray of light falls on a plane mirror angle of 45° Through whatangle is it turned on reflection ?​

Answer»

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°
