I suppose a laser makes more sense to me because we are directly stimulating emission of discrete energy in the first place (or so I understood). With an accelerating point charge, the old field and the new field could be measured from an infinite number of points, so where does it become...
Recently I learned in E&M the nature of creation of electromagnetic radiation, specifically in the context of an accelerating charge, as a ripple in the field. My quarrel is this:
We can measure the electric field surrounding a point charge from an infinite number of points; the field is...
