A transparent slab of thickness d has a refractive index n (z) that increases with z. Here z is the vertical distance inside the slab, measured from the top. The slab is placed between two media with uniform refractive indices n 1 and n 2 (> n 1 ), as shown in the figure. A ray of light is incident with angle 
from medium 1 and emerges in medium 2 with refraction angle 
with a lateral displacement 
.
Which of the following statement (s) is (are) true?
is independent of n 2
is dependent on n (z)
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
(A, C, D)
From Snell’s Law
n 1 sin 
= n sin 
= n 2 sin 
The deviation of ray in the slab will depend on n (z)
Hence, 
will depend on n (z) but not on n 2 .
