In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. What's the physics and are there optical analogies? In this example of a sound wave, the period of one cycle of this wave is 0.5 seconds, and the frequency of this wave is 2 cycles per second or 2 Hertz (Hz). The lower the frequency, the fewer the oscillations. Is it similar? If . Comparing two waves of different wavelengths, a higher frequency doesnt always indicate faster movement, although it can. Because of this, sound is lost to heating of the medium it is propagating through. Another thing that happens that can lead you to think that low frequency sounds attenuate quicker is that if you record yourself one time being close to the microphone and another time being farther away, you'll notice that the farther you are the more the lowest frequencies are picked up. Period is the reciprocal of the frequency. Consequently, a sound wave can only propagate through a limited distance. Humans can hear after 20Hz and even though we cant hear below 20Hz, we can definitely feel it.
