(a) Consider two pairs of medium pair A(1 & 2), pair(3 & 4). With the help of table point out in which medium light speeds up as it moves to pair A and in pairB respectively.
Serial Number 1 2 3 4 Medium Water Benzene Turpentine Alcohol Refraction Index 1.33 1.50 1.47 1.36
(b) Find refractive index of benzene with respect to water.



Dear Student,

Please find below the solution to the asked query:

When light travels in Pair B, that is from medium 3 to 4 refractive index decreases. So The light will speed up when travelling in pair B (from 3 to 4). 

Refractive index of Benzene with respect to water is 1.51.33=1.12

Hope this information will clear your doubts about this topic.
