Question

Define the term absolute refractive index. The absolute refractive index of diamond is 2.42. What is the meaning of this statement? Refractive indices of media A, B C and D are given below: (5) Media Refractive index A 1.33 B 1.44 C 1.52 D 1.65 In which of these four media is the speed of light (i) minimum and (ii) maximum ?Find the refractive index of medium C with respect to medium B.

Answer 1

the speed of light in medium with respect to vaccum
N = C/V
THE SPEED OF LIGHT IN DIAMOND IS 2.42
MXIMUM = D BECAUSE HIGHEST RI
MINIMUN = B LOWEST RI
Ncb = 1.52/1.44
152/144 = 1.05
