What is power of a parallel faced glass slab?

The lateral shift produced in a parallel sided glass slab depends on

What is meant by lateral shift ?Explain for a given slab,what is the quantity that determines lateral shift?Obtain the expression for lateral shift for refracion throug a parallel sided glasss slab.

For what angle of incidence,the lateral shift produced by a parallel sided glass plate is maximum?

For what angle of incidenc e,the lateral shift produces by a parallel sided glass plate is zero?

A ray of light is incident at an angle of 60^@ on one face of a rectangular glass slab of thichness 0.1 m and refractive index 1.5.Calculate the lateral shift produced.

Two charges are placed a finite distance apart. If a glass slab is placed between them, force between them will:
