In 1887 Heinrich Hertz sparked a charge back and forth across a gap and caught the wave it threw across his lab — the first radio, and proof that light is a wave in the electromagnetic field.
What radiates is not a moving charge but an accelerating one. Drag the charge at a steady speed and nothing leaves; only the turnaround — the acceleration — kinks a field line hard enough to pinch off and stream away at the speed of light.
The pattern is a doughnut: strong broadside, exactly zero along the axis. That empty cone is why a vertical antenna is deaf to a signal coming from straight overhead.
Radiated power climbs as the fourth power of frequency (P ∝ ω⁴). The same law, applied to sunlight scattering off air molecules, is why the daytime sky is blue.
Something in the simulation stopped unexpectedly — the lesson continues without it. Nothing you did was wrong; you can move on.
