To remind you, in Physics 101 you learned that the momentum ~p of an object with mass m traveling with velocity ~v is given by ~p = m~v. The magnitude of the momentum of a photon has been found to be given by |~pphoton| = h/λ, where h is Planck’s constant and λ is the photon’s wavelength. The direction of the photon’s momentum is the direction in which the photon is moving. Suppose that a hydrogen atom that is initially...

Activity Manual 22 on Photons does not discuss the momentum of a photon, but the photon’s momentum and momentum conservation are important for Positron Emission Tomography, a medical imaging technique that you will be studying in class soon. So in this homework you will learn about photon momentum and momentum conservation in the context of photon emission from hydrogen atoms. To remind you, in Physics 101 you learned that the momentum ~p of an object with mass m traveling with...
