Question

A monochromatic light wave with wavelength $\lambda_1$ and frequency $V_1$ in air enters another medium. If the angle of incidence and angle of refraction at the interface are $45^{\circ}$ and $30^{\circ}$ respectively, then the wavelength $\lambda_2$ and frequency $v_2$ of the refracted wave are.

Select the correct option:

$\lambda_2=\lambda_1, \mathrm{v}_2=\sqrt{2} \mathrm{v}_1$

$\lambda_2=\frac{1}{\sqrt{2}} \lambda_1, \mathrm{v}_2=\mathrm{v}_1$

$\lambda_2=\sqrt{2} \lambda_1, \mathrm{v}_2=\mathrm{v}_1$

$\lambda_2=\lambda_1, v_2=\frac{1}{\sqrt{2}} v_1$
