Base of a prism the end on which a prism may be supposed to stand is called the base of the prism.

Height of a prism the perpendicular distance the ends of a prism is called the height of the prism.

What is meant by base of a prism?

When light travels from a rarer medium to a prism which is a denser medium, light ray bends towards the base of the prism. Is the statement true of false?

Axis of a prism the straight line joining the centres of the ends of a prism is called the axis of the prism.

Length of a prism the length of a prism is the portion of the axis that lies between the parallel ends.

A ray of light incident on one of the face of a prism as shown. After refraction through this surface ray is incident on base of the prism. The refractive index of the prism is sqrt(3) . The net deviation of the ray due to prism is
