A right angle prism (45^@-90^@-45^@) of refractive index mu has a plate of refractive index mu,(mu_1 lower than mu) cemented to its diagonal face.The assembly is in air.A ray is incident at face AB as shown in Fig.3.15 . Calculate the angle of incidence at face AB for which the ray strikes the diagonal face at critical angle.
