The refractive index of glass is 1.5. Calculate the speed of light in glass. The speed of light in air is `3.0 xx 10^(8) ms^(-1)`.

Text Solution

Verified by Experts

Velocity of light in glass
`=("Velocity of light in vacuum")/("Refractive index of glass")`
`=(3.0xx10^(8)ms^(-1))/(1.5)=2.0xx10^(8)ms^(-1)`
