The diagram below shows two successive scatterings at locationsA and B. In the first scattering, a photon of wavelength 𝜆1 hits afree electron at A resulting in a photon of wavelength 𝜆2 thatmoves at an angle 𝜃1 to the incident direction. The second photonhits an electron at B and scatters at an angle 𝜃2 to the directionof the second photon resulting in a photon of wavelength 𝜆3.Determine the angle 𝜃1 (in degrees) if 𝜃2 = 47.0° and the totalshift in wavelength of the combined scattering is 3.98 ✕ 10−3nm.
