This question already has an answer here:
I am struggling to understand the concept of a "light wave" From what I understand, when a charged particle accelerates, it creates a disturbance in electromagnetic field that travels through space. Is a photon a single oscillation then? Often times we are shown "light waves" being created by something that is continuously oscillating, so is each oscillation its own photon? The graphics I've seen of light waves often show many many sinusoidal oscillations in the E and B field, is this one photon as it moves through time or is this many disturbances in space?
Basically trying to visualize what happens when a photon is created. I feel comfortable with the idea of oscillating electric and magnetic fields but can't quite rap my head around whether a photon is a single piece of energy or the composition of many oscillations? Does this oscillation create a disturbance that moves in a single direction (perpendicular to direction of acceleration) or all directions (like a pebble dropped into a pond?) Apologies if these questions are a bit convoluted, struggling to rap my head around what's happening.
Thanks so much!
