Question

If the refractive index of benzere is 2.419, what is the speed of light in benzene?

Answer 1

Answer:

$v=1.24\times 10^8\ m/s$

Explanation:

Given that,

The refractive index of benzene is 2.419

We need to find the speed of light in benzene. The ratio of speed of light in vacuum to the speed of light in the medium equals the refractive index. So,

$n=\dfrac{c}{v}\\\\v=\dfrac{c}{n}\\\\v=\dfrac{3\times 10^8}{2.419}\\\\v=1.24\times 10^8\ m/s$

So, the speed of light in bezene is $1.24\times 10^8\ m/s$.
