Use the following information to answer the next question. An XDray photon that has a wavelength of 2.000 x 10-10 m collides with a stationary electron. Stationary electron Photon incident The scattered XOray photon, which has a wavelength of 5.068 x 10-10 m, returns along the in the initial path Scattered electron Scattered photon Determine whether the collision is elastic or inelastic. 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
