Q.

The de Broglie wavelength ( $λ$ ) associated with a photoelectron varies with the frequency ( $v$ ) of the incident radiation as, [ $v_{0}$ is threshold frequency]:

A
$λ \propto \frac{1}{( v - v _{0} )}$
B
$λ \propto \frac{1}{( v - v _{0} ) ^{\frac{1}{4}}}$
C
$λ \propto \frac{1}{( v - v _{0} ) ^{\frac{1}{2}}}$
D
$λ \propto \frac{1}{( v - v _{0} ) ^{\frac{3}{2}}}$

Solution

According to de-Broglie wavelength equation
