A ray of light experiences minimum deviation by an equilateral prism P. Now two prisms Q and R made of the same material as that of P are arranged as shown in the figure. The ray of light will now experience, (The dimensions of P, Q and R are same.) __________ .(A) larger deviation(B) no deviation(C) same deviation as that due to P(D) total internal reflection

Figure (a) is part of an equilateral prism of figure (b) as shown in figure which is a magnified image of figure (c).
Therefore , the ray will suffer the same deviation in figure (a) and figure (c). so, the correct option is (c) same deviation that due to P.
