For refractin of light through a prism

A

For every angle of deviation there are two angles of incidences

B

The light travelling inside an equilateral prism in necessarily parallel to the base when prism is set for minimum deviation

C

There are two angles of incidence for maximum deviation

D

Angle of minimum deviation will increase if refractive index of prism `(mu_(p))` is increased keeping the refractive index of the outside medium `(mu_(s))` uncharged if `mu_(P) gt mu_(S)`.
