A 25.0-pm x-ray photon scatters off a free electron at A
(Fig. P27.26), producing a photon of wavelength A' traveling at
an angle 0 = 40.0° relative to the first photon's direction. This
second photon scatters off another free electron at B, produc-
ing a photon with wavelength A" and moving in a direction
directly opposite the first photon. Determine the wavelengths
