Explain lateral shift for the refraction from rectangular glass slab.

Light from a luminious point on the lower face of a rectangular glass slab , 2 cm thick, strikes the upper face and the totally reflected rays outline a circle of 3.2 cm radius on the lower face. Find the refractive index of the glass.

Explain reflection and refraction of waves.

Explain the refraction of light through a glass slab with a neat ray diagram (AS_(5))

A mixed ray of red and green colour incidents obilquely on surface of rectangular glass slab. After passing through slab, the rays of red and violet colour emerging out surface parallel to incident surface are…..

Refractive index of glass relative to water is 9/8. What is the refractive index of water relative to glass? (AS_(1))

A water tank is partially fill upto 2 m height. As shown in figure, 0.1 m thick glass slab is placed on water surface. If refractive indices of water and glass are 1.3 and 1.5 respectively, what will be virtual depth of object placed at bottom when it is viewed from top ?

Explain plane wave refraction from denser to rarer medium using Huygen's principle.

A narrow beam of light is incident on a glass plate of refractive index 1.6. It makes an angle 53^@ with normal to the interface. Find the lateral shift of the beam at the point of emergence, if thickness of the plate is 30 mm. (Take sin 53^@ = 0.8.)

The angle of incidence at which reflected light totally polarised for reflection from air to glass (refractive index n), is ......
