Question

The speed of the light in a diamond is 1, 24, 000
km/s. Find the refractive index of diamond if the
speed of light in air is 3,00,000 km/s. (AS)
(Ans: 2.42)​

Answer 1

Answer:

The refractive index of the diamond = 2.4

Explanation:

The speed of the light in a diamond is 1,24,000 km/s, the speed of light in air is 3,00,000 km/s

To find the refractive index of the diamond

Solution:

We know, 

Refractive index of the medium

$= \frac{speed \: of \: light \: in \: air}{speed \: of \: the \: medium \: in \: air}$

⟹ Refractive index of diamond

$\frac{300000 \: km /s</p><p>}{124000km/s</p><p> } = \frac{300}{124} = 2.4$
