Question
A given ray of light suffers minimum deviation in an equuilateral prism P. Additional prism Q and R of identical shape and of the same material as P are now added as shown in the figure. The ray will be
Options
A.greater deviation
B.no deviation
C.same deviation as before
D.total internal deviation
Solution
Figure (a) is part of an equilateral prism of figure (b) as shwon in figure hich is a magnified of figure (c). Therefore, the ray will suffer the same deviation in figure (a) and figure (c).
