Assertion (A): Skiers uses air glasses. Reason(R) : Light reflected by snow is partially polarised.

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

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

Polarised glass is used in sun glasses because:

Polarised glass is used in sum glasses because:

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
