Mar 31, 2015 · In light propagation, oscillation does not mean any movement in space. It is the value of the electromagnetic field, at one given point in space, that oscillates. The picture that you quote does not represent the movement in space, but the electromagnetic field value as a function of time.

Here is the simple explanation as to why electromagnetic waves oscillate. As you probably already know, electromagnetic waves are generated by moving electrons. An electron generates an electric field.
Mar 23, 2018 · Oscillating electrons up and down an antenna does create oscillating waves of photons but the OP is asking about the wave itself. In other words you could send electrons up an antenna one time only and still create a wave of photons radiating outward.
Assuming we have a beam of light traveling from left to right, the electric field of the wave can be illustrated as a sine wave that oscillates up and down in space. But the thing that oscillates is not an object or photon or anything physical, it's just the value of the electric field.
Jul 16, 2018 · To get things off the ground, a surprising practical application of the wave nature of light. Polarization refers to the direction in which the electric field of an electromagnetic wave oscillates. The electric field can oscillate in any plane — horizontal, vertical or anything in between.
Electromagnetic Wave: Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields. The direction of the electric field is indicated in blue, the magnetic field in red, and the wave propagates in the positive x-direction.

In fact, this gives us a way of describing how the wave propagates: The wave causes a single point to oscillate, which in turn causes a wave to be generated, which then vibrates another point, and so on.
