The critical angle of a transparent crystal is 30^(@) . What is the polarising angle of the crystal?

The critical angle of a transparent crystal is 60^(@) . Then its polarizing angle is

For a transparent crystal, the critical angle is 30^@ .What will be the value of polarising angle for that crystal?

The critical angle of a transparent crystal is 45^(@) . Then its polarizing angle is

The polarising angle for a piece of glass for green light is 60^(@) . Find the angle of minimum deviation for green light for its passage through 60^(@) prism, made of the same glass. Given 1sin 60^(@) = 0.866, tan 60^(@) = 1.732 .
