WebThat is: they don't have the oomph the strip electrons from atoms. Radio waves can cause some materials to propagate their signal, but for the most part radio waves go through … WebSo radio waves pass through walls because the molecules in the wall can't absorb them. The electrons aren't in the right orbitals and a single photon of that wavelength can't be used by the electron, so it's ignored. The whole wave does push on the electrons a little bit, but no significant amount of signal is lost by one wall.
