Q. 2

A certain material has refractive indices 1.56, 1.60 and 1.68 for red, yellow and violet light respectively. A Calculate the dispersive power. B Find the angular dispersion produced by a thin prism of angle 6 made of this material.

Answer :

Given that


Refractive index of red light = μr = 1.56


Refractive index of yellow light = μy = 1.60


Refractive index of violet light = μv = 1.68


Refracting angle of prism=A= 6.0°


A Dispersive power = ω =


= [substituting values]


=


B Angular dispersion = δ =


=


=


=


Thus, the angular dispersion produced by the thin prism is 0.72°
