(A) The frequency $f$ of light remains constant when it enters a different medium. The frequency is given as $f = 5 	imes 10^{14} \ Hz$.In air,the speed of light is $c = 3 	imes 10^8 \ m/s$.The wavelength in air is $\lambda_{	ext{air}} = \frac{c}{f} = \frac{3 	imes 10^8}{5 	imes 10^{14}} = 0.6 	imes 10^{-6} \ m = 600 \ nm$.When light enters a medium with refractive index $\mu = 2$,the wavelength changes to $\lambda_{	ext{medium}} = \frac{\lambda_{	ext{air}}}{\mu}$.Substituting the values,$\lambda_{	ext{medium}} = \frac{600 \ nm}{2} = 300 \ nm$.

$A$ monochromatic light of frequency $5 \times 10^{14} \ Hz$ travelling through air is incident on a medium of refractive index $2$. What will be the wavelength of the refracted light (in $nm$)?
