Problem

The speed of light in vacuum is

3.0\times10^{8}\,\text{m s}^{-1}

. In turpentine the speed of light is

2.0\times10^{8}\,\text{m s}^{-1}

, while in kerosene it is

2.25\times10^{8}\,\text{m s}^{-1}

. a. Calculate the absolute refractive index of (a) turpentine, (b) kerosene. b. Which of the two liquids is optically denser?
