If the wavelength of electromagnetic (em) radiation is equal to the de Broglie wavelength ($\lambda$) of an electron moving with a velocity of $2 \times 10^{6}\text{ m s}^{-1}$, then what is true about their momenta?
  • (a)Their momenta are equal.
  • (b)Photon of electromagnetic radiation has greater momentum than the electron.
  • (c)Their momenta cannot be compared, as one is a photon and the other is a particle.
  • (d)Electron has greater momentum than the photon of electromagnetic radiation.
