A prism is set for minimum deviation. The angle of incidence is double the angle of refraction. If `mu = sqrt2` calculate the angle of the prism.

An equilateral prism is set for minimum deviation. If the angle of incidence is 45^@ then the angle of minimum deviation is

A glass prism of refracting angle of 60^@ is set for minimum deviation. The angle of minimum deviation is 30^@ . Find Refractive index of glass with respect to air.
