Answer:
Momentum, \[p=\frac{h}{\lambda }\] As both electron and photon have same wavelength, so they have equal momentum. Relativistic energy of a particle, \[E=\sqrt{m_{0}^{2}{{c}^{4}}+{{p}^{2}}{{c}^{2}}}\] But for a photon, \[{{m}_{0}}=0\] and for an electron, \[{{m}_{0}}>0\]. Hence the electron has more energy than the photon.
