Given that, the velocity of light in quartz =1.5×108m s-1and velocity of light in glycerine =94×108m s-1. If a slab made of quartz is placed in front of an object kept in glycerine (as shown in the figure), then the shift of the object produced by slab is

Options:

Answer:
A
Solution:


n=velocity of light in vaccumvelocity of light in medium ,

velocity of light in vacuum = 3×108m s-1

nquartz=2 ; nglycerine=43nquartznglycerine=24/3=32=μrel

shift = t 1 - 1 μ rel = 1 8 - 1 3 / 2 = 6 cm
