Question

the refractive index of water is 4/3 if the speed of light is 3*10^8m/s find the speed of light
​

Answer 1

Answer:

It travels 225×$10^6$ m/s

Explanation:

$\frac{n_1}{n_2} =\frac{v_2}{v_1}$

⇒$\frac{1}{\frac{4}{3} } = \frac{v_2}{3*10^8}$

=>9*$10^8$/4= $v_2$

=>9*25*$10^6$

=>225×$10^6$
