If sound waves travel by pushing particles back and forth, then how exactly do electromagnetic/radio waves travel through the vacuum of space and dense matter? Are they emitting… stuff? Or is there some… stuff even in the empty space that they push?
In: Physics
Sound is a mechanical wave, literally the vibration of atoms.
Electromagnetic waves are force carries of the electromagnetic force. As in, all through spacetime there is an electromagnetic field, this field produces energy excitations, this is what a photon is.
It is not actually a wave, we only describe it as this when we use the Schrodinger (and other) interpretation(s) of quantum mechanics.
