WebJul 21, 2024 · How does waves travel through space? Waves travel through space by vibrating the particles that make up the medium through which they are passing. The particles of the medium vibrate in response to the wave, passing on the energy of the wave to the next particle in the medium. WebThese types of waves will very easily pass through most materials.

WebOct 20, 2024 · A short answer is that penetration depth of electromagnetic waves in a material is proportional to square root of resistivity, inversely proportional to square root of permeability and, most importantly for this context, inversely proportional to the square root of the frequency of the signal.

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. greenhouse clearance ukWebBut high frequencies are more sensitive to reflection, so they will have a harder time passing through walls and obstacles in general.
