Question

an electromagnetic wave carrying momentum p can transfer maximum amount of momentum of zp fsctoary object it reflects from (such as a mirror), In the quantum mechanical analysis of scattering (e a single photon with a stationary charged particle (such as electron or proton), how does this on a simple classical picture change? a The photon can only impart a discrete, allowed amount of momentum to the charged particle, given by hf/c (where h is Planck's constant, f is frequency of the photon, and c is speed of light) b) The amount of momentum the photon can impart is limited by the simultaneous requirements of energy and momentum conservation in scattering of the photon from the charged particle. c The photon can more easily transfer a larger amount of momentum (up to the maximum value of given classically) to particles of less mass (like electron) than larger mass (like proton). If the photon is not energetic enough to overcome the inertia of the charged particle, the photon will not be able to transfer any momentum to the charged particle. d) 27. What is the magnitude of the spin angular momentum of the electron? a) h b) e) Additional information is necessary to answer this question

Explanation / Answer
