If the refractive index of glass is 1.5....

If the refractive index of glass is 1.5. Find the velocity of light in glass. (Velocity of light in vacuum `= 3 xx 10^(8) m//s`)

Text Solution

Verified by Experts

We have `mu = (c)/(v)`
`1.5 = (3 xx 10^(8))/(v)`
`v = (3 xx 10^(8))/(1.5) = 2 xx 10^(8) m//s`
