What are the values of angle of incidence ∠i and angle of reflection

1.	What are the values of angle of incidence ∠i and angle of reflection ∠r for normal incidence oflight on a plane mirror ?
Answer» When the LIGHT ray is incident normally on plane mirror surface it means the angle between mirror surface and light ray is 90°. This means the angle between incident light ray and normal is 0º which is CALLED angle of incidence. As angle of incidence is 0° angle of refelection is ALSO 0°. ( By law of reflection of light)
