Expert Answer

The angle of minimum deviation is defined as :

 

Where nprism is the index of refraction of the prism Since n varies with wavelength (i.e., n = n(λ)), the

angle of minimum deviation also varies, but it is constant for any particular wavelength. As the n is maximum for violet light as per cauchy's formula ,the angle is most for violet light.
