The de-Broglie wavelength of an electron is same as the wavelength of a photon. The energy of a photon is ‘x’ times the K.E. of the electron, then ‘x’ is: (m-mass of electron, h-Planck’s constant, c - velocity of light)

Assertion : If the wavelength lamda of photon and de Broglie wavelength of electron are same , their energy is also same. Reason : Momentum of both the particles is same by de Broglie hypothesis.

Momentum of a photon of wavelength lamda is

Show that the do Broglie wavelength lamda of an electron of energy E is given by the relation lamda = =h/(sqrt2mE)

According to de-Broglie hypothesis, the wavelength associated with moving electron of mass 'm' is 'lambda_(e)' . Using mass energy relation and Planck's quantum theory, the wavelength associated with photon is 'lambda_(p)' . If the energy (E) of electron and photonm is same, then relation between lambda_e and 'lambda_(p)' is
