There's a property of all quantum fields called "phase". Feynman 
describes this as being *something like* a turning hand on a clock face 
that just goes around. (See the books I mentioned.) Don't make too much 
of it other than that, except to note that every kind of oscillation or 
rotation has some kind of property that is phase. Phase is a property 
like momentum is a property, and it doesn't make sense to ask what 
momentum is made of or what is momentuming. Likewise, phase is a 
property of the object and it doesn't make sense to ask what the phase 
is made of or what is rotating.

So when you see any kind of waviness and you want to ask, what is waving 
back and forth, it's the phase of the field.

Note, this does NOT mean back and forth MOVEMENT to and fro. That's only 
true for certain kinds of waves where there is actual displacement 
through space, but is not a general feature.
