In most physics textbooks, the oscillating electric and magnetic fields generated by a moving photon are depicted as above.
In this image, the photon is moving along x axis, the electric field is oscillating long z axis ( in z-x plane), and the magnetic field is oscillating along y axis (in x-y plane).
I am having two fundamental problems with this picture.
Does the electric field oscillate strictly in the x-z plane only? Does it completely vanish just a miniscule distance away from this plane? This does not make sense intuitively.
If there is just a single photon moving along x axis, the electric and magnetic fields must die out after the photon has passed. This means that the amplitude of E and B at a given point on x axis must fade out as the photon goes away. So how does this picture change in the case of a single moving photon?
