An electron and a photon have same de Broglie wavelength. It implies that they have the same

The de Broglie hypothesis postulates that every moving particle has an associated wave nature. The relationship between the de Broglie wavelength (λ) and the linear momentum (p) of a particle is given by the equation λ = h/p, where h is Planck's constant. This fundamental relation applies to both material particles like electrons and massless particles like photons. According to this formula, the momentum p is inversely proportional to the wavelength (p = h/λ). Therefore, if an electron and a photon possess the same de Broglie wavelength, they must necessarily have the same linear momentum. Their energies differ because the energy-momentum relationship for a photon is E = pc, whereas for a non-relativistic electron, it is E = p²/(2m). Similarly, their speeds differ as photons always travel at the speed of light, while an electron's speed depends on its mass and momentum.
