The wavelength of light, while it is passing through water is 540 nm . The refractive index of water is $4/3$ . The wavelength of the same light when it is passing through a transparent medium having refractive index of $3/2$ is
$____$ nm .

Question

The wavelength of light, while it is passing through water is 540 nm . The refractive index of water is

4/3

. The wavelength of the same light when it is passing through a transparent medium having refractive index of

3/2

is

____

nm .

Accepted Answer

Correct answer: B. (b) Frequency of light is constant in all media. In water with refractive index 4/3, wavelength is 540 nm . The wavelength in vacuum is _0=540 43=720 nm. In a medium with refractive index 3/2, the wavelength is = 7203/2=720 23=480 nm.
