Draw a ray diagram to show the angle of deviation when a ray of light passes through a glass prsim.

Draw a ray diagra to show refraction of a ray of monochromatic light passing through a glass prism.

The angle of deviation of a ray of light refracted through a parallel glass slab is

What is lateral displacement ? Draw a ray diagram showing the lateral displacement of a ray of light when it passes through a parallel sides glass slab.

Draw a labelled ray diagram to show how a ray of light passes through a parallel sided glass block: a) if it hits the glass block at 90^(@) (that is perpendicular to the glass block).

Draw a ray diagram to show the refraction of light through a glass prism. Hence obtain the relation for the angle of deviation in terms of the angle of incidence, angle of emergence and the angle of the prism.

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.
