The reflected and refracted rays are observed to be perpendicular to each other, when ray of light is incident at an angle of 60∘ on a transparent block. The refractive index of the block is

A light ray is travelling from air to glass. True reflected and refracted rays are perpendicular to each other. If the angle of incidence in air is I the refractive index of glass is

A light ray is travelling from air to glass. True reflected and refracted rays are perpendicular to each other. If the angle of incidence in air is I the refractive index of glass is

A ray of light incident on a medium at polarising angle.what will be the angle between the reflected and the refracted rays? Or, an unpolarised ray of light is incident on a rectangular glass block at Brewster's angle. What will be the angle between the reflected and the refracted rays?

A ray of light from a rarer medium strikes a denser medium at angle of incidence 60°. The reflected and refracted rays are perpendicular to each other. The refractive index of denser medium and angle of deviation respectively are

Light is incident on a glass plate at an angle of 60^@ . The reflected and refracted rays are mutually perpendicular to each other. The refractive index of the plate is

A ray of light is incident on liquid surface such that reflected and refracted ray are perpendicular to each other. If refractive index is 1.4, find angle of incident.
