Calculate the dispersion and deviation ( mean) produced by a flint glass prism placed in the position of minimum deviation with respect to the mean colour. The angle of prism is `60^(@)`. Also calculate the dispersive power of the prism. Index of refraction of flint glass for blue light=0.667 and that for the red light =1.643.
