I_d = ε₀·dΦ_E/dt. Maxwell's missing piece for the Ampère-Maxwell law.

E ⟂ B ⟂ direction. Sinusoidal transverse waves traveling at c = 3×10⁸ m/s.

From radio (km) → gamma (pm). Visible band 380–750 nm. Toggle bands.

S = (1/μ₀) E×B. Energy flow direction & intensity of EM wave.

P = I/c (absorbed) or 2I/c (reflected). Light pushes objects.

Tune wavelength and watch frequency adjust. Cross-spectrum interactive map.
