Originally Answered: Why does lower frequency Radio Waves travels farther than shorter ones? Even a good pair of headphones like Sennheiser HD-650 struggle with lower frequencies: So if it sounds like high frequencies travel farther with headphones, it's because headphones are poor at producing low frequencies and your ear is poor at picking them up. But it may have less problem in propagate to things. They also allow a wider band for modulating signals, so you can obtain higher frequency transmission. Does hair loss from extensions grow back?

One advantage of lower frequencies is that the signals have better penetration, meaning they pass through objects such as walls with less attenuation. In particular: So with very weak sounds, high frequencies seem to travel further? As sound waves travel through a medium, they lose energy to the medium and are damped. The question presupposes that low-frequency radio waves don't travel as far as high, but this is not generally the case. In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. Higher frequency waves are able to pass through the atmosphere entirely and reach the ground. Low-frequency sound has a long wavelength and so can only be reflected by large objects. Whats the difference between low frequency and high frequency radio waves? Low frequency waves are produced by slow vibrations while high frequency waves are produced by fast vibrations.So low frequency waves have less energy because they are produced by slow vibrations.
