Vibration of Photons

  1. Sep 6, 2011 #1
    Do photons vibrate or oscillate in any way?

    Photons are not little BBs, they are electromagnetic waves. They have all the properties we associate with electromagnetic waves: E field, B field, frequency and wavelength. It's just that they represent a minimal excitation of the electromagnetic field: you can't have half a photon.

    If photons can knock out electrons from their orbits why can't they behave as BBs. Isn't any kind of matter wave associated with them?

    GarryS, Photons carry energy and momentum, as all electromagnetic waves do, and some or all of it can be transferred to other particles. The fact that this transfer happens as a discrete event rather than continuously is a general feature of quantum mechanics, not a special property of photons.

    The wavefunction used to describe a photon is just the electromagnetic field itself, specifically the vector and scalar potentials A and φ.
