Question

the speed of light in a transparent medium is 2.44into 10 to the power 8 m/s.find the refractive index of the medium.........please help me guys...​

Answer 1

Hello Mate,

Here is your answer,

We Know that refractive index

$= \frac{velocity\: of \: light \: in \: vaccum}{velocity \: of \: light \: in \: specified \: medium} \\ \\ = \frac{ v_{v}}{ v_{m} } \\ \\ in \: this \: case \\ \\ v_{v} = 3 \times {10}^{8} (velocity \: of \: light) \\ \\ v_{m} = 2.44 \times {10 }^{8} (given)$

So refractive Index =

$\frac{3 \times {10}^{8} }{ {2.44 \times10 }^{8} } \\ \\ = \frac{3}{2.44} \\ \\ = 1.22$

So, the refractive index is 1.22

Hope it helps:)

Plz follow:)
