Part A Further support for the photon model of electromagnetic waves comes from Compton scattering, in which x-rays scatter from electrons, changing direction and frequency in the process. Classical electromagnetic wave theory cannot explain the change in frequency of the x-rays on scattering, but the photon model can. Suppose an x-ray photon is moving to the right. It has a collision with a slow-moving electron, as in the figure. The photon transfers energy and momentum to the electron, which recoils at a high speed. The x-ray photon loses energy, and the photon energy formula E = hf tells us that its frequency must decrease. The collision looks very much like the collision between two particles. ( Figure 1) What happens when the x-ray photon scatters from the electron? Its speed increases Its speed decreases Its speed stays the same Submit Previous Answers Request Answer × Incorrect; Try Again; 5 attempts remaining Part B What happens when the x-ray photon scatters from the electron?
