A beam of light is partially reflected and partially refracted from a surface. The angle between reflected and refracted light ray is `90^(@)`. If the angle of refraction is `30^(@)`, the angle of incidence is

In polarisation by reflection of light angle between reflected light and refracted light is

In the light polarised by reflection, the angle between reflected and refracted ray is :

Rays of light fall on a glass plate, the refractive index of which is n. If the angle between the reflected and refracted rays is 90^@ , then the angle of incidence is

A light is incident on a refractive medium. The light is partially reflected and partially refracted. If both the reflected and refracted rays are mutually perpendicular, then determine the angle of refraction. Refractive index of medium is 1.47.

A ray of light is incident at an angle I on a glass slab of refractive index mu . The angle between reflected and refracted light is 90^(@) . Then the relationship between I and mu is

When the light is polarised by reflection, what is the angle between the reflected and the refracted rays ?
