The refractive index of a liquid is 1.5. If the velocity of light in vacuum is 3.0 x 10\(^8ms^{-1}\), the velocity of light in the liquid is
n = \(\frac{\text{speed in air}}{\text{speed in glass}}\)
1.5 = \(\frac{3 \times 10^4}{\text{speed in glass}}\)
Speed in glass = 3 x 10\(^8\)m/s / 1.5
= 2 x 10\(^8\)m/s
There is an explanation video available below.
