When angle of incidence is 60^@ on surface of a glass slab, it is found that the reflected ray is completely polarised. The velocity of light in 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)

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

Light is incident at an angle i on a glass slab. The reflected ray is completely polarished . The angle of refraction is

Light is incident at an angle i on a glass slab. The reflected ray is completely polarished . The angle of refraction is

When a light ray in air is incident on glass at 57^(@) , the reflected ray is completely polarised. If the same ray is incident on water at an angle theta , also the reflected ray is completely polarised. Then

When light is incident from air to glass at an angle 57^@ , the reflected beam is completely polarised. If the same beam is incident from water to glass, the angle of incidence at which reflected beam is completely polarised will be
