A right angled prism of refractive index is placed in a rectangular block of refractive index , which is surrounded by a medium of refractive index 3, as shown in the figure. A ray of light 'e' enters the rectangular block at normal incidence. Depending upon the relationships between , and 3, it takes one of the four possible paths 'ef', 'eg', 'ch', or 'ei'. 14 H3 Match the paths in List I with conditions of refractive indices in List II and select the correct answer using the codes given below the lists: List I P. ef Q. eg R. e h S. ei Codes: P (A) 2 (B) 1 (C) 4 (D) 2 Q 3 2 1 3 R 1 4 2 4 S 4 3 3 1 14 1. 2. 3. 4.
