The difference between angle of minimum deviation of violet and red rays in the spectrum of white light from a prism is 2^(@) . If angle of minimum deviation of mean ray is 48^(@) , the dispersive power of material of the prism is

Assertion : If the angles of the base of the prism are equal, then in the position of minimum deviation, the refracted ray will pass parallel to the base of prism. Reason : In the case of minimum deviation, the angle of incidence is equal to the angle of emergence.

A beam of monochromatic light is incident at an angle of 55^(@) on one face of an equilateral prism . The angle of deviation is delta and the angle of emergence is 46^(@) . If the angle of minimum deviation (delta_(m)) for the same prism is 45^(@) , then

A prism can produce a minimum deviation delta in a light beam. If three such prisms are combined, the minimum deviation that can be produced in this beam is

Two identical prism of index sqrt3 are kept as shown in the figure. A light ray strikes the first prism at face AB. Find, (a) the angle of incidence, so that the emergent ray from the first prism has minimum deviation. (b) through what angle the prism DCE should be rotated about C so that the final emergent ray also has minimum deviation.

A beam of monochromatic light is incident at i= 50^(@) on one face of an equilateral prism, the angle of emergence is 40^(@) , then the angle of minimum deviation is :

When white light passes through a glass prism one gets spectrum on the other side of the prism in the emergent beam the ray which is deviating least is or Deviation by a prism is lowest for
