A prism with refracting angle `60^@` gives angle of minimum deviation, `53^@, 51^@ and 52^@` for blue, yellow and red light respectively. What is the dispersive power of the prism ?

A prism with a refracting angle of 60^@ gives angles of minimum deviation 53^@,51^@ and 52^@ for blue,red yellow light respectively.What is teh dispersive power of the material of the prism?

The angles of minimum deviations are 530 and 51° for blue and red colours respectively produced in an equilateral glass prism. The dispersive power is

If the refracting angle of a prism is 60^@ and the minimum deviation is 30^@ , then the angle of incidence is
