A ray of light of wavelength

600\,\text{nm}

propagates from air into a medium. If its wavelength in the medium becomes

400\,\text{nm}

, the refractive index of the medium is

Solution: 👈: Video Solution

\;\; \lambda_{\;\text{medium }\;} = \frac{\lambda_{\;\text{air }\;}}{\mu}

Or,

400 \;=\; \frac{600}{\mu}

\therefore \mu \;=\; \frac{600}{400} = 1.5
