Hello everyone. I have tried to do as much research as my layman mind will allow on how an electromagnetic wave propagates in relation to how a sound wave for example does. I understand that an acoustic wave is longitudinal and works on compression and that a light wave is a transverse wave that propagates perpendicular to the direction. But I just don't understand how exactly it is propagating. I mean I know that science probably doesn't 100% understand it either but can someone clear up any of it at all? Or is it a complete 100% mystery? For example let's say light is a packet of photons and they are traveling in a straight line, what is it exactly that is acting as a wave? If it is the photons that are transversely waving from side to side, what is it that's making them go from one side then come back to the other instead of flitting away in random directions? Is it the 'magnetic field' property? Is there basically a magnetic field around each photon that is making it swing like a pendulum in frequencies? How does it work.......? Thank you.
