When light of particular wavelength falls on a plane surface at an angle of incidence 60^(@) then the reflected light becomes completely plane polarised Find the refractive index of surface material and the angle of refraction through it.

A ray of light strikes a glass plate at an angle of incidence 57^(@) . If the reflected and refracted rays are perpendicular to eachother, calculate critical angle for total internal reflection at glass air interface.

A ray of light strikes a glass plate at an angle of 40^(@) . If the reflected and refracted rays are perpendicular to each other the index of refractive of glass is

When the angle of incidence on a material is 60^(@) , the reflected light is completely polarised. The velocity of the refracted ray inside the materials is (in m//sec^(-1))

Light is incident at an angle i on a glass slab. If the reflected ray is completely polarised , then the angle of refraction is

The angle of incidence at which reflected light is totally polarized for reflection from ait to glass (refractive index n), is :
