A prism has refracting angle equal to pie/2. It is given the gama is the angle of minimum deviation and beta is the deviation of the ray entering at grazing incidence. Prove that sin gama = sin^2 Beta.

refracting angle A so that there is no emergent ray irrespective of the angle of incidence? What should be the minimum value of refractive index of a prism
