Question

velocity of light in quartz is 1 5×10^8 m/s and velocity of
light in glycerine is (9/4)×10^8m/s now a slab of quartz is
placed in glycerine thickness = 18cm object is at 20cm left side of
the slab observer is at right what is the shift of the object
produced by slab ?

Deleted · Accepted Answer

First find the value of the refractive index for the two
mediums
n(of quartz with respect to glycerine)=(9/4)*1/1 5=3/2

Now lateral shift = t(1 - 1/n)
= 0 18*(1 - 2/3)
=0 06 m=6 cm

velocity of light in quartz is 1.5×10^8 m/s and velocity of light in glycerine is (9/4)×10^8m/s. now a slab of quartz is placed in glycerine . thickness = 18cm .object is at 20cm left side of the slab .observer is at right.what is the shift of the object produced by slab ?
