Question

Light enters from air to kerosene having refractive index of 1.47. What is the speed
of light in kerosene, if the speed of light in air is 3x10⁸ m/s?

Answer 1

Answer:

Explanation:the answer is given below :

Answer 2

Answer:

$2.04 \times {10}^{8}$

Explanation:

Given,

refractive index of light from air to kerosene = 1.47

speed of light in air =

$3 \times {10}^{8}$

refractive index = speed of light in air

speed of light in kerosene

1.47 = 3×10^8

x

x = 3x10^8

1.47

x = 2.04×10^8
