Can UHF radio waves pass through walls?

Question

If not, what kind of radio waves can pass through walls?

Answer 1

UHF can pass through walls of typical buildings. Most of the RF band gets through walls without significant attenuation.

Answer 2

The question is tantamount to asking why easy waves get absorbed in partitions on a similar time as radio waves do no longer. The phenomenon of resonance is on the middle of this. I’ll illustrate by using an occasion. evaluate an L-R-C circuit, the place C is a variable capacitor, so as that the circuit is tuneable. This circuit could have a resonant frequency of a million/?(LC). If the circuit is coupled to an aerial, then incoming radio waves of frequency a million/?(LC) will set the circuit in resonance, on a similar time as radio waves of distinctive frequencies will bypass the circuit by using and circulate away it unaffected and undisturbed. For the circuit to ‘%. up’ radio waves of different frequencies C could want to be altered by using tuning the circuit. a similar component happens while e.m. waves attempt to penetrate a wall. If the ability variations of the atomic and molecular strategies in the wall tournament the energies of the incoming e.m. waves, the linked photons get absorbed; if there is not any tournament, the waves bypass right this moment through. a similar component happens with Magnetic Resonance Imaging contraptions. a very solid magnetic field aligns the protons in the hydrogen atoms of the water molecules of ,say, the suggestions and a radio frequency e.m. wave is surpassed in the direction of the suggestions. while the frequency is adjusted so as that the ability of the photons fits the version in energies of two a threat quantum spin states of the protons, the photon power gets absorbed, and the absorption get registered in a detector on the different area. This types the muse of the imaging technique. Your question could for this reason be responded in one observe: RESONANCE. Billy c’s clarification is at a chemical point and is authentic in its very own words. The deeper clarification is rooted in quantum mechanics.
