Document Summary
Compton effect, momentum of a photon, de broglie. Arthur compton studied how photons interacted with electrons (the same way as we examined a 2-d momentum collision). When a very high-energy photon (x-ray) collides with a free electron, it gives some of its energy to the electron and a lower-energy photon scatters off the electron. It was difficult for compton to show that the momentum was conserved, since a light particle had no mass, so he derived the following formula knowing einstein"s equation that relates energy and mass: Therefore, the momentum is described as: where: p is the momentum of the photon in ns h is planck"s constant, 6. 626x10-34 js. Is the wavelength of the photon in m. Compton was able to use this to show that momentum was conserved. Calculate the momentum of a photon that has a frequency of 5. 71x1014hz. By now, scientists had come to believe that light was a particle and a wave.
