Why low frequency can travel longer distance? 1 Why do lower radio frequencies travel further? The distance that the sound needs to travel is one of the key considerations in determining the frequency of the signal. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Due to the penetration power of high frequency radio waves in general, is the major limitation of FM staions where the AM uses ionosphere for reflection and hence it covers more distance.

At any time, day or night, there is a window of usable frequencies created by the reflecting properties of the ionosphere. Why do all sound waves travel at the same speed? Air molecules scatter light in this way because they are very small (much smaller than the wavelength of visible light). 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.
