The refractive index of medium A is 1.5 and that of medium B is 1.33. If the speed of light in air is `3 xx 10^(8)` m/s, what is the speed of light in medium A and B respectively ?

A

`2xx 10^(8)` m/s and `1.33 xx 10^(8)` m/s

B

`1.33 xx 10^(8) ` m/s and `2xx 10^(8)` m/s

C

`2.25 xx 10^(8) ` m/s and `2 xx 10^(8)` m/s

D

`2 xx 10^(8) ` m/s and `2.25 xx 10^(8)` m/s
