According to de-Broglie hypothesis, the wavelength associated with moving electron of mass m is${\lambda }_e^{}$. Using mass energy relation and Planck's quantum theory, the wavelength associated with photon is${\lambda }_p^{}.$If the energy$\left(E\right)$of electron and photon is same then relation between${ }^{}{\lambda }_e^{}$and${\lambda }_p^{}$is
