Because the waves are reflected, they can reach radio receivers that are very far away from the radio tower. Air molecules, such as N2, O2, CO2 are roughly 3 to 4 ngstroms in diameter. Does low or high frequency travel faster? 2 Why do you lose your FM radio signal as you travel farther away from the radio station transmitter? Since its wavelengths range from 101 km, respectively, it is also known as the kilometre band or kilometre wave. 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. This cookie is set by GDPR Cookie Consent plugin. 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 . Air molecules scatter light in this way because they are very small (much smaller than the wavelength of visible light). Why downlink frequency is lower than uplink? Without going into quantum stuff, the simple explanation is that waves can only interact with objects whose size is similar to the wavelength of the wave. The lower the frequency, the fewer the oscillations. They differ only in rate of information sent. 1 Why do lower radio frequencies travel further?
