  • The refractive index of glass and water with respect to air are 3/2 and 4/3 respectively. If  the speed of light in glass is <img alt="2 \times 10 ^ 8 m/s" src="https://entrancecorner.codecogs.com/gif.latex?2%20%5Ctimes%2010%20%5E%208%20m/s"

The refractive index of glass and water with respect to air are 3/2 and 4/3 respectively. If  the speed of light in glass is 2 \times 10 ^ 8 m/s, find the speed of light in water.

N_g = 3/ 2\\\\ N_w = 4/3

Absolute refractive index

= speed of light in vacuum / speed of light in medium 

Speed of light in glass = 2 \times 108 m/s

speed of light in vacuum = 3/2 \times 2 \times 108 m/s

                                          3 \times 108 m/s

speed of light in water = 

\frac{3 \times 108 m/s}{4/3}\\\\ = 2.25 \times 108 m/s
