Low frequency radio waves do not travel very far through the atmosphere and are absorbed rather quickly. How do people make money on survival on Mars? So the amplitide decreases $\propto 1/ r^4$. That's because sound is a pressure wave that relies on moving molecules around to get where it's going, and it can get there faster or slower depending on what those molecules are like. 1 Why low frequency can travel longer distance? Hope this helps In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Wave always carry energy infinite distance. The cookie is used to store the user consent for the cookies in the category "Performance". Sound waves travel slower in cold air than warm air because the molecules hit faster and transmit the pulse in less time in warm air. Here is a graph of the attenuation of sound at difference frequencies (accounting for atmospheric pressure and humidity): As you can see, low frequencies are not absorbed as well. Instead, FM waves pass through the ionosphere and out into space. Does it depend on the amplitude or energy of the wave? Quick Answer: Why Do Low Frequency Sound Waves Travel Further.

From Wikipedia (Wavelengths), "The wavelengths of sound frequencies audible to the human ear (20 Hz20 kHz) are thus between approximately 17 m and 17 mm, respectively." My experience is that this feature is not recognized by noise mediation experts or local officials. Does homeowners insurance cover damage to neighbor property fire? Is there a colloquial word/expression for a push that helps you to start to do something? How do you identify neurotypical disorders? You're right though that in general terms, lower frequency waves are diffracted more. Waves of different wavelengths can have the same frequency. So for sound waves.is absorption the main difference? As it turns out, the ionosphere reflects certain frequencies of radio waves. OTOH, while wearing the headphones there's little difference since you're in the near field where neither frequency range has decayed substantially at all. Lower frequency wave tend to pass though bigger object with lesser absorb or reflect. Googling about this quickly got me more confused. Why does sound attenuate in air differently in different situations? and our Because both are simply EM waves. Do low frequency waves carry longer distance than high frequency waves?
