Question

The absolute refractive index of a transparent
medium is 5/3. Find the speed of light in the
medium.
(Ans: 1.8 x 108 m/s)​

Answer 1

Answer:

speed of light=

$\frac{speed \: in\: air}{nu} \\ \\ \frac{3 \times 10 {}^{3} \times 3 }{5} \\ \\ \frac{9}{5} \times {10}^{3} = 1.8 \times {10}^{3}$
