Question

speed of light in vacuum is 3 ×10 raise to 8 metre per second find the absolute refractive index of medium in which light travel with the speed of 1.4
10 into ​

Answer 1

ur question is incomplete....

Answer 2

Answer:

Ratio of speed of light in two medium is equal to ratio of their refractive index , so

$\frac{ \mu}{1} = \frac{1.4 \times {10}^{8} }{3 \times {10}^{8} } = \frac{14}{30} = \frac{7}{15} \\ \\ \mu \approx0.467$
