you CAN, in fact, hit airwaves. air is quite corporeal, and you can certainly punch it.

now, i know that you meant EM (electromagnetic) waves, but those, too, can be affected (albeit weakly) by any change in electric field. since human bodies contain electromagnetic potentials, fist pumping, or whatever form of “hitting” you prefer will actually have an effect on “airwaves” via the standard EM equations (maxwell’s laws, etc).

i may have just answered my own “ask tony” question (why did i not have friends in high school?)
