Question
The diagram shows 4 pairs of transparent media with various indexes of refraction. A red laser beam is incident upon the interface producing reflected and refracted beams. The top medium is the same in all cases, but the bottom medium is different in all cases. Which two of the following statements are correct? Mark both for full credit. Select one or more: O a. The upper and lower media have the same index of refraction in A. O b. The lower medium in B has the highest index of refraction O c. The lower medium in A has a higher index of refraction than the lower medium in D O d. The lower medium in C has the same index of refraction as the the lower medium in D O e. The incident ray is in the upper medium in cases A, B and C.Explanation / Answer
(a) The upper and lower media have the same index of refraction in A.
(d) The lower medium in C has the same index of refraction as the lower medium in D.
