The de-Broglie wavelength () associated with a photoelectron v

Question

Easy

Solving time: 2 mins

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

λ \propto \frac{1}{( v - v _{0} ) ^{\frac{1}{4}}}

λ \propto \frac{1}{( v - v _{0} ) ^{\frac{3}{2}}}

λ \propto \frac{1}{( v - v _{0} )}

λ \propto \frac{1}{( v - v _{0} ) ^{\frac{1}{2}}}

de-Broglie wavelength

(λ)

for electron is given by

λ = \frac{h}{2 m K.E}

Also, according to photoelectric effect

KE = h ν - h v_{0}

On substituting the value of

KE

Eq

(i), we get

λ = \frac{h}{2 m \times ( h v - h v _{0} )}

λ \propto \frac{1}{( v - v _{0} ) ^{1/2}}
