Draw a ray RS.

Draw a ray PQ.

A ray of light falls normally on a rectangular glass slab. Draw a ray diagram showing the path of the ray till it emerges out of the slab.

Draw a ray diagram to show the formation of the image as specified in the part a.

Draw a ray diagram showing the formation of image of a point object by a plane mirror.

A ray of light, after refracting through a concave lens, emerges parallel to the principal axis. Draw a ray diagram to show the incident ray and its corresponding emergent ray.

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 ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation. How is the angle of emergence related to the angle of incidence in the position.

Draw a ray diagram to illustrate how a ray of light incident obliquely on one face of a rectangular glass slab of uniform thickness emerges.

Draw a ray diagram showing the path of rays of light when it enters with oblique incidence (i) from air into water , (ii) from water into air.

Draw a ray diagram to show a right angled isosceles prism may be used to ''bend the path of light rays by 90^(@) . Write the necessary condition in terms of the refractive index of the material of this prism for the ray to bend to 90^(@) .
