Problem

The absolute refractive index of glycerine is 1.47. Calculate the speed of light in glycerine. Take the speed of light in vacuum as

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

. a)

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

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

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

2.9\times10^{7}\,\text{m s}^{-1}
