Given: The wavelength of the electron and photon is
(a)
The momentum of a particle is given as,
Where, the wavelength is
By substituting the given values in the above formula, we get
Thus, the momentum of electron and photon is
(b)
The energy of the photon is given as,
Where, the energy of a photon is
By substituting the given values in above formula, we get
Thus, the energy of the photon is
(c)
The kinetic energy of an electron is given as,
Where, the momentum of a electron is
By substituting the given values in above formula, we get
Thus, the kinetic energy of the electron is
