Question

is refractive index of a medium is 2.4 and c=3x10^8 find speed of light in medium

Answer 1

1.25 x 10^8 m/s

Answer 2

The refractive index ($n$) of a medium is defined as the ratio of the speed of light in vacuum ($c$) to the speed of light in the medium ($v$).

The formula is:

$n = \frac{c}{v}$

Given $n = 2.4$ and $c = 3 \times 10^8$ m/s.

Rearranging the formula to find $v$:

$v = \frac{c}{n}$

Substitute the given values:

$v = \frac{3 \times 10^8 \text{ m/s}}{2.4}$

$v = 1.25 \times 10^8 \text{ m/s}$
