A beam of y-rays with 2.23 MeV energy, all travelling in the same direction (call it, along the x axis) interact with Al (aluminum) foil. It is observed that some photons deviate from their original direction by 30°, whereas others by 60°. Ignoring Rutherford scattering -scattering from the nucleus- (which is very scarce), estimate the difference in the wavelengths of photons scattered with 30° and 60°. Express your answer in pm (picometer=10-12 m). Answer: A beam of y-rays with 2.23 MeV energy, all travelling in the same direction (call it, along the x axis) interact with Al (aluminum) foil.
