A light of wavelength `6000 A` in air, enters a medium with refractive index 1.5 Inside the medium its frequency is….Hz and its wavelength is ….`A`

Text Solution

Verified by Experts

Here, `lambda = 6000Å = 6 xx 10^(-7)m`,
`mu = 1.5, lambda' = ?, v' = ?`
`lambda' = (lambda)/(mu) = (6000)/(1.5) = 4000 Å`
`v' = v = ( c)/(lambda) = (3 xx 10^(8))/(6 xx 10^(-7)) = 5 xx 10^(14)Hz`
