The speed of light in vacuum is 3.0 x 108ms..

Question 1 Report

The speed of light in vacuum is 3.0 x 108ms-1. If the refractive index of a transparent liquid is $\frac{4}{3}$ , then the speed of light in the liquid is

0.44 x 10 8ms-1

2.25 x 10 8ms-1

3.0 x 10 8ms-1

4.0 x 10 8ms-1

4.33 x 10 8ms-1

Answer Details

n = $\frac{speed in air}{speed in water}$

$\frac{4}{3}$ = $\frac{3 \times 10^{8}}{v}$

v = 2.25 x 10 8ms-1
