Question

(a) Arrange the optical densities of the media in ascending order. Given that the refractive index of media A, B, C and D are 1.5, 1.14, 1.0 and 2.42 respectively.
(b) A ray of light has a path as shown in the figure above. Comment on the refractive index of medium 1 and 2.
(c) The refractive index of a medium 'x' with respect to 'y' is 2/3 and the refractive index of medium 'y' with respect to medium 'z' is 4/3. Calculate the refractive index of medium z with respect to x. It's a physics question.

Answer 1

Ans (c)

Ans (a) Optical density is directly proportional to refractive index
In ascending order.....
C
B
A
D

Ans (b) since the light ray has not refracted
Refractive index of medium 1 and medium 2 is same
