A ray of light passes through two slabs of same thickness. In the first slab 
, waves are formed and in the second slab 
. Find refractive index of second medium with respect to first.

Text Solution
Verified by ExpertsThe correct answer is:
C
One wave means one wavelength. So, if t is the thickness of slab, λ the wavelength and n the number of waves, then
or 
(at t is same) or 
Now, refractive index of second medium w.r.t first medium is
