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.

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.

An isosceles prism has one of the refracting surfaces silvered. A ray of light is incident normally on the refracting face AB. After two reflections, the ray emerges from the base of the prism perpendicular to it. Find the angle of the prism.

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

When does a ray passing through a prism deviate away from the base of the prism ?

The base of a right prism is a right angled triangle. The measure of the base of the right angled triangle is 3 m and its height 4 m. If the height of the prism is 7 m. then find (a) the number fo edges of the prism. (b) the volume of the prism. (c) the total surface area of the prism.

The base of a right prism, whose height is 2 cm, is a square. If the total surface area of the prism is 10 cm^(2) , then its volume is :

An equilateral glass prism kept on a table has refractive index of mu = sqrt(2) . It is illuminated by a narrow laser beam having power P_(0) and wavelength l. The path of the laser beam inside the prism is parallel to the base of the prism. Calculate change in weight of the prism due to the incident laser beam.
