White light is incident on one of the refraction surfaces of a prism of angle 5∘∘. If the refractive indices for red and blue colours are 1.641 and 1.659 respectively, the angular separation between these two colours when they emerge out of the prism is?

θ = (n(B) - n(A) ) x A = (1.659 - 1.641) x 5 = 0.09 degree
