The refractive index of kerosene is 1.44 . Find the velocity of light through kerosene.

Text Solution

Verified by Experts

Given
Velocity of light through air , ca=`3xx10^(8) ms^(-1)`
To find : Speed of light through kerosene,
`c_(k)= ?`
Refractive index of kerosene , `mu_k =1.44`
`mu_k =(c_(a))/(c_(k)) implies 1.44`
`mu_(k) =(3xx10^(8))/(c_(k))=2.083 xx 10^(8) ms^(-1)`
Speed of light through kerosene,
`c_(k)=2.083 xx 10^(8) ms^(-1)`

Assertion : If the refractive index of the medium is high (denser medium) the velcoity of the light. In that medium will be small. Reason : Refractive index of the medium is inversely proprotional to the velocity of the light.
