Use the following information to answer the next question. An X-ray photon that has a wavelength of 2.000 x 10-10 m collides with a stationary electron. Stationary electron Photon incident The scattered X-ray photon, which has a wavelength of 5.068 x 10m, retums along the in the initial path Scattered electron Scattered photon Verify that this collision is elastic. Marks will be awarded based on the relationships among the two physics principles* that you state, the formulas that you state, the substitutions that you show, and your final answer. *The physics principles are given on the data sheet
