The ratio of the wavelengths of a photon and that of an electron of same energy E will be [m is mass of electron ]

If m is the mass of an electron and c the speed of light, the ratio of the wavelength of a photon of energy E to that of the electron of the same energy is

The de-Broglie wavelength of an electron is the same as that of a 50 ke X-ray photon. The ratio of the energy of the photon to the kinetic energy of the electron is ( the energy equivalent of electron mass of 0.5 MeV)

The wavelength lambda_(e ) of an photon of same energy E are related by

The ratio of de-Broglie wave length of a photon and an electron of mass 'm' having the same kinetic energy E is: (Speed of light=c)

If m is the mass of an electron and c is the speed of light then the ratio of wavelength of a photon of energy E to that of the electron of the same energy is

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.

The wavelength lamda_(e) of ann electron and lamda_(p) of a photon of same energy E are related by
