Unpolarised light is incident from air on a plane surface of a material of refractive index u! At a particular angle of incidence mu it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation ?

At what angle of incidence should light beam strike a glass slab of refractive index (mu=sqrt3) , such that the reflected and refracted rays are perpendicular to each other?

A light ray travels from vacuum into a medium of refractive index mu . If angle of incidence is twice the angle of refraction then calculate the angle of incidence.

Light enters at an angle of incidence in a transparent rod of material of refractive index mu . The light once entered into it will not leave it through its lateral face, whatsoever be the value of angle of incidence, if
