Answer :

Given that


Minimum Deviations by Red = δr = 38.40


Minimum Deviations by Yellow = δy = 38.70


Minimum Deviations by Violet = δv = 39.20


If A is the angle of prism having refractive index μ, then the angle of minimum deviation is given by



Therefore,


Dispersive power =


=


=


=


=


So, the dispersive power of the medium is 0.0204
