1 of 1

Application +4 | -1

Monochromatic light of frequency

5\,\, \times \,\,{10^{14}}\,\,\mathrm{Hz}

travelling in vaccum enters a medium of refractive index

\mathrm{1}\mathrm{.5}

. It wavelength in the medium is

View answer and explanation

Correct option: A

4000\,\,{A^0}

Option A (

4000 \,{A^0}

) is correct because the wavelength in the medium is calculated by dividing the wavelength in vacuum by the refractive index of the medium.
