Question

12. Sunita has given four slabs X, Y, Z and W with refractive indices 1.45, 1.41, 1.52 and
1.30 respectively. She has to arrange these slabs in order of decreasing speed of light
through them. Her friend Sanjana helped her in this task and also tell her about the
relationship between speed of light and refractive index.
(a) How is refractive index related to speed of light?
(b) What is the order of speed of light of slabs is obtained by Sanjana?
(c) What values are displayed by Sanjana?



​

Answer 1

Answer:

a if refractive index is more than the speed of light is slow if refractive index is less the sleed of light if fast

b w y x z

c 1 .45 1.41 1.3 1.52
