Monochromatic light of wavelength `lambda_1` travelling in medium of refractive index `n_1` enters a denser medium of refractive index `n_2`. The wavelength in the second medium is

Light of wavelength lambda_(1) enters a medium with refractive index n_(2) from a medium with refractive index n_(1) . What is the wavelength of light in second medium ?

A monochromatic beam of light of wavelength lambda and frequency f travelling in vacuum enters a diamond of refractive index 2.4 . Then

Light of wavelength 6000 Å in air enters a medium of refractive index 1.5. What will be its wavelength in the medium ?

A monochromatic beam of light is travelling from medium A of refractive index n_(1) to a medium B of refractive index n_(2) . In the medium A , there are x number of waves in certain distance . In the medium B , there are y number of waves in the same distance . Then , refractive index of medium A with respect to medium B is ...
