To observe the Compton Effect we need a source of high-energy photons and a suitable spectrometer to observe the frequency shift in photons as they recoil. The source of short-wavelength photons is not much of a problem—a 137Cs source produces photons at a wavelength λ = 1.88 × 10−12 m. Actually, the more common unit for expressing…
