So the wave moves like. a wave, it moves up and down, up and down. But how do photons move? Do they follow the same path or do they just go straight forward without oscillating?
The question is a bit tricky. Actually, a photon is the electromagnetic wave. Photons are quanta of the field. You can imagine a photon as the fact that there is an oscillation in the field.
However, if you are in an approximation that allows you to treat photons as particles, then I would say that the don't oscillate, they just move on at light speed.
I know, the answer is not complete, I should explain better how photons can be defined, but perhaps someone can do it better than me.
