    What are prisms? Prisms are nothing but a portion of a refracting medium bordered by two plane surfaces that are inclined at a finite angle. Prisms have a thicker portion called the base of the prism and a tapering portion called the apex of the prism. Prisms are oriented with their apex towards the direction of deviation. What happens to light when it enters a prism? Light has particle and wave characteristics. When it travels through the thicker base of the prism, the particle form of light has to travel a longer distance than at the apex of the prism, this difference causes light to bend towards the base of the prism. The power of a prism to bend light is measured in prism diopters (PD). One prism diopter will shift light by 1 cm at 1m distance. Calibration of Prism Prisms made of glass are calibrated in Prentice position. They should be held with the back surface perpendicular to the line of sight. Plastic prisms and prism bars are calibrated by the angle of minimum deviation. They
