The de Broglie wavelength ( $\displaystyle \lambda$ ) associated with a photoelectron varies with the frequency ( $\displaystyle \nu$ ) of the incident radiation as, [ $\displaystyle \boldsymbol{v}_{\mathbf{0}}$ is threshold frequency] :
Official answer
(1)
$\displaystyle \lambda \propto \frac{1}{\left(v-v_0\right)^{\frac{1}{2}}}$
