Define Angle of incidence

Right or wrong . If wrong , write the correct sentence : Angle of incidence is always greater than angle of reflection .

Angle of incidence is less than critical angle : Partial reflection :: Angle of incidence is greater than critical angle : ____

A ray is incident at an angle of incidence i on one surface of a small angle prism (with angle of prism A) and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , then the angle of incidence is nearly equal to:
