Question 1 Report

The refractive index of a liquid is 1.5. If the velocity of light in a vacuum is 3.0 x 10

^{8} m s^{? 1}

, the velocity of light in the liquid is

1.5 x 10⁸ ms^-1

2.0 x 10⁸ ms^-1

3.0 x 10⁸ ms^-1

4.5 x 10⁸ ms^-1

Answer Details

The velocity of light in the liquid can be calculated using the formula for the refractive index (n) of a medium: v = c / n, where c is the velocity of light in a vacuum and n is the refractive index of the medium. In this case, n = 1.5, so the velocity of light in the liquid would be v = 3.0 x 10^8 m/s / 1.5 = 2.0 x 10^8 m/s. Therefore, the velocity of light in the liquid is 2.0 x 10^8 m/s
