Question

The absolute refractive indices of four media A, B, C and D are given in the
following table
A B C D
1.5 1.33 2.4 1.7
In which medium (a)the optical density is maximum and in which medium (b)the
speed of light maximum?
(ii) The refractive index of a dense flint glass is 1.65 and for alcohol it is 1.36 with
respect to air. What is the refractive index of dense flint glass with respect to
alcohol?

Answer 1

(ii)

(i) a. the density is maximum in 2.4(diamond)

b. the speed of light is maximum in 1.33 (water)
