The wavelength λ

Answer :

Let λ be the wavelength of the photon. The wavelength of De-Broglie’s wavelength is given by,

Where, m = mass of electron

v = velocity

The kinetic energy of the electron is given by,

Photon has energy as,

Taking ration of kinetic energy and energy we get,

Thus, the energy of a photon is (2lmc/h) times the kinetic energy of electron.
