Speed of photon . Let be the wavelength of the photon. The de Broglie wavelength of the electron is Given . Now |

A proton is fired from very far away towards a nucleus with charge where is the electronic charge. It makes a closest approach of to the nucleus. The de Broglie wavelength (in units of ) of the proton at its start is : (take the proton mass, |
