Question

What is the speed of light in Benzene if it's refractive index is 1.50?

Answer 1

speed of light in Benzene=speed of light in vaccum/refractive index of Benzene

=3 x 10^8/1.5

=2 x 10^8 m/sec
hence speed of light in Benzene =2 x 10^8 m/sec

Answer 2

Answer:

The speed of light in benzene is 2,00,000 m/sec.

Explanation:

Benzene is colourless liquid with gasoline like odour due to the hydrocarbon properties, highly inflammable and volatile in nature.

To find the speed of the light in the liquid benzene we take refractive index of the benzene compound as 1.5

• The speed of the light in the given compound = “speed of the light in vacuum/refractive index of the compound”.
• The speed of the light in the Benzene = speed of the light in vacuum/refractive index of the Benzene.

The speed of the light in the Benzene $=\frac{3,00,000}{1.5}=2,00,000 \quad m / \sec$

Therefore, the speed of light in Benzene is 2,00,000  m/sec.
