The wavelength of light coming from a so...

The wavelength of light coming from a sodium source is 589 nm. What will be its wavelength in water? Refractive index of water 1.33.`

Text Solution

Verified by Experts

The wavelength in water is `lamda=lamda_0/mu where lamda_0` is the wavelength in vacuum and `mu` is th refractive index of water. Thus,
`lamda=589/1.33=4443nm.`
