A converging beam of light is incident on a right angled isosceles prism as shown in the Figure. The marginal rays in the beam are incident at angle +- theta . The refractive index for the glass of the prism is mu = 1.49 (= (1)/(sin 42°)) . Find the maximum value of theta for which no light comes out of the hypotenuse surface.

STATEMENT -1: A white parallel beam of light is incident on a plane glass-vacuum interface as shown. The beam my not undergo dispesion after suffering deviation at the interface (The beam is not incident normally on the interface.) STATEMENT -2: Vacuum has same refractive index for all colours of white light.

A beam of unpolarised ligth is incident on a glass-air interface. Showing a suitable ray diagram,that light reflected from the interface is totally polarised,when mu=tan i_B ,Where mu is the refractive index of glass with respect to air and i_B is the Brewster's angle.

A converging set of ray, traveling from water to air, is incident on a plane interface. In the absence of the interface, the rays would have converged to a point O, 60 cm above the interface. However, dur to refraction the rays will bend. At what distance above the interface will the rays actually converge?
