Refractive index of glass w.r.t water is `9//8`. What is the speed of light in water ? Given speed pf light in glass is `2 xx 10^(8) m//s`.

The R.I. of the glass w.r.t. glycerine is ((1.5)/(1.4)) . What is the speed of light in glycerine , if the speed of light in glass is 2 xx 10^(8) m/s ?

The refractive index of glass is 1.5. What is the speed of light in glass? (Speed of light in vacuum is 3.0 × 10^8 m s )

(a) The refractive index of glass is 1.5. What is the speed of light in glass? ("Speed of light in vacuum is "3.0 xx 10^(8) m s^(-1)) (b) Is the speed of light in glass independent of the colour of light? If not, which of the two colours red and violet travels slower in a glass prism?
