The absolute refractive index of glass and water are 3/2 and 4/3 , respectively. If the speed of light in glass is 2 × 10^8 m/s, calculate the speed of light in :(a) vacuum(b) water
![The speed of light in a medium is 2.25 xx 10^(8) m//s. Calculate absolute refractive index of the medium. The speed of light in a medium is 2.25 xx 10^(8) m//s. Calculate absolute refractive index of the medium.](https://d10lpgp6xz60nq.cloudfront.net/web-thumb/96609881_web.png)
