Which of the following statement is `//` are correct about the refraction of light from a plane surface when light rays is incident in denser medium. `[` C is critical angle `]`

Options

A. The maximum angle of deviation during refraction is `pi/2-C`, it will be at angle of incidence is greater than C.
B. The maximum angle of deviation for all angle of incidences is `pi-2C`, when angle of incidence is slightly less than C.
C. If angle of incidence is less than C then deviation increases if angle of incidence is also decreased.
D. If angle of incidence is greater than C then angle of deviation decreases if angle of incidence is increased.

Answer

D
