Necessary cookies are absolutely essential for the website to function properly. by Arna Bee October 18, 2021 Low frequency sound waves are able to travel further than high frequency sound waves for a variety of reasons. Not all radio waves travel farther at night than during the day, but some, short and medium wave, which AM radio signals fall under, definitely can given the right conditions. Similarly, high frequency sound will result in more molecular collisions, which will increase energy loss there. The way I understand energy, is you need more energy to travel further, like adding gas to a car. 3 Do higher or lower frequencies travel faster? Does it depend on the amplitude or energy of the wave? In addition the points made in Brandon enright's excellent answer, you need to consider that sound sources aren't really idealised point sources.

Hope this helps In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. The very simplistic explanation is: lower frequency waves travel further because they can interact with (bounce off) the ionosphere under certain conditions, whereas frequencies above a few 10s of MHz cannot 'bounce' off the ionosphere. But opting out of some of these cookies may affect your browsing experience. One advantage of lower frequencies is that the signals have better penetration, meaning they pass through objects such as walls with less attenuation. Comments ( 13) Not all radio waves travel farther at night than during the day, but some, short and medium wave, which AM radio signals fall under, definitely can given the right conditions. An additional factor is that low frequency means long wavelength, and longer waves are diffracted more around edges, and this makes it possible for the low frequency sound to effectively curve over hills so that the sound can get places even though the source cant be seen. Sound waves travel at a constant speed but the wavelength of the waves depends on the frequency. Does low or high frequency travel faster? Thus, the transmitted power is constant. How do people make money on survival on Mars? Why do certain types of sound seem to fade faster? rev2023.3.1.43266.

To imagine frequency relate to size of object is not so intuitive, Air is a non-dispersive medium so the speed of sound doesn't vary with frequency. It does not store any personal data. Optically flat means that surface irregularities are small compared to the wavelength of light. In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. The time to complete a cycle is the period. The proximity effect means lower frequencies are picked up the, But wavelength is porportional to the inverse of frequency, so saying "actually it's about wavelength" is equivalent to saying it's about frequency, @BinaryFunt If it is sound wave it can be vary in speed so in each situation it could be same frequency but difference wavelength and vice versa.
