Question

In a Compton scattering experiment, an x-ray photon scatters through an angle of 17.0° from a free electron that is initially at rest. The electron recoils with a speed of 1,560 km/s. (a) Calculate the wavelength of the incident photon. X Enter a number differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully nm (b) Calculate the angle through which the electron scatters. 80.29 Need Help? Read It
