The greater the energy of a photon , the :

The ratio of the energy of a photon of wavelength 3000 "Å" to that of photon of wavelength 6000 "Å" is :

If we express the energy of a photon in KeV and the wavelength in angstroms , then energy of a photon can be calculated from the relation

If we express the energy of a photon in KeV and the wavelength in angstroms , then energy of a photon can be calculated from the relation

If we express the energy of a photon in KeV and the wavelength in angstroms , then energy of a photon can be calculated from the relation

The order of energy of X-ray photon is :-

An electron and a photon have got the same de- Broglie wavelength. Prove that total energy of electron is greater than energy of photon.
