A monochromatic light wave with wavelength $\displaystyle \lambda_1$ and frequency $\displaystyle \nu_1$ in air enters another medium. If the angle of incidence and angle of refraction at the interface are $\displaystyle 45^{\circ}$ and $\displaystyle 30^{\circ}$ respectively, then the wavelength $\displaystyle \lambda_2$ and frequency $\displaystyle \nu_2$ of the refracted wave are:
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle \lambda_2=\frac{1}{\sqrt{2}} \lambda_1, \nu_2=\nu_1$
