Question 1 Report

The refractive index of liquid is 1.5. If the velocity of light in vacuum is 3.0 x 108ms-1, the velocity of light in the liquid is

1.5 x 108m-1

2.0 x 108m-1

3.0 x 108m-1

4.5 x 108m-1

9.0 x 108m-1

Answer Details

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

1.5 = $\frac{3 \times 10^{4}}{speed in glass}$

speed in glass = 2 x 108ms-1
