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

If 'm' is the mass of an electron and 'c' is 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

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

The ratio of wavelength of a photon and that of an electron of same energy E will be

The ratio of wavelength of a photon and that of an electron of same energy E will be

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

The de Broglie wavelength of an electron is the same as that 50 keV 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 is 0.5 MeV)
