How can wifi penetrate through walls when visible light can

WebNow I would draw the simple conclusion that atleast one part of EM radiation must not be penetrating any metal surface and since EM radiations cannot survive solely as E or M radiation any sort of radiation penetrating metal surface must not be possible. But in fact x-rays do pass metal surfaces. WebRadio waves penetrate walls to some degree. Lower frequency radios (e.g. AM in the 1 MHz range) penetrate most buildings walls while higher frequency such as microwaves don’t. The attenuation through wall varies by the type of wall material, the walls thickness and by the frequency of the radio. im a thotWebIn general though, the penetration of an EM wave is determined by the absorption of whatever you're trying to penetrate.
