A ray of light strikes the surface of a rectangular glass slab such that the angle of incidence in air is (i) `0^(@), (ii)45^(@)`. In each case, draw a diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.

A ray of light is incident perpendicularly on a glass slab. The angle of incidence is 90^(0) .

Ordinary light is incident on the upper surface of a glass slab at theh polarizing angle. Then

Draw the diagram given below and clearly show the path taken by the emergent ray:

When a ray of light enters a glass slab from air.

When a ray of light passes from air to glass, for what angle of incidence, the ray will not be deviated?

A ray of light strikes a glass slab 5 cm thick, making an angle of incidence equal to 30^(@) . (a) Draw a ray diagram showing the emergent ray and the refracted ray through the glass block. The refractive index of glass is 1*5 . (b) Measure the lateral displacement of the ray. The sin 19*5^(@)=1//3 .

A ray of light travelling in air strikes the surface of glass at angle of 45^(0) . The angle of refraction in the glass will be :

A ray of light strikes a transparent rectangular slab of refractive index sqrt(2) at an angle of incidence of 45^(@) . The angle betweent the reflected and refracted rays is

When a ray of light enters a glass slab from air

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
