A material medium X has a refractive index 1.5 and another medium Y has a refractive index of 1.44.
(a) Calculate the velocity of light in each of these media.
(b) In which medium will travel faster ?

Explanation

`{:("Medium X","Medium Y"),(mu_(x)=1.5,mu_(y)=1.44),(mu_(X)=(c )/(V_(X)),mu_(X)=(c )/(V_(x))),(V_(x)=(c )/(mu_(x))=(3xx10^(8))/(1.5),v_(y)=(c )/(mu_(y))=(3xx10^(8))/(1.44)),(=2xx10^(8)m//s,=2.08xx10^(8)m//s):}`
(b) Light will travel faster in medium Y when compared to medium X.
