Show that a light ray will pass through an equilateral glass prism `(mu = 1.5)`. If the angle of incidence is greater than `30^(@)`.

Light ray passes through an equilateral prism (mu = 1.5) such that the angle of incidence is equal to angle of emergence and is (3)/(4) th of the angle of deviation. Calculate the angle of deviation.

A ray of light passes through an equilateral prism (mu=1.5) . The angle of minimum deviation is (Given sin 48^(@)36'=0.75 )

A ray of light passes through an equilateral glass prism in such a manner that the angle of incidence is equal to the angle of emergence and each of these angles is equal to 3/4 of the angle of the prism. The angle of deviation is
