We know it's electromagnetic waves, but as it says we tend to ignore the latter part.
Having just studied for (and passed! yay me!) my amateur radio license exam, I've been mulling over this common omission of consideration of propagating magnetics. Phase too: we're so focused on frequency that we overlook phase. Polarization is also underrated, with a study last year suggesting "infinite bandwidth" (so said news reports) when used creatively.
Revisiting basics can reveal wonderous things.
