In a Compton scattering experiment, an x-ray photon scatters through an angle of 21.0° from a free electron that is initially at rest. The electron recoils with a speed of 2,520 km/s.(a) Calculate the wavelength of the incident photon.___nm(b) Calculate the angle through which the electron scatters.
