Why FM is not used for long distance communication? Does a square wave "smooth out" in the air? In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. If so, our speech signal is low frequency signal, why it is not travelling further? Red light waves have wavelengths around 700 nanometers (nm), while blue and purple light have even . Why dont we use low frequencies for modulation? Low frequency (low energy) light has a longer wavelength than high frequency (high energy) light, and is usually much closer to the size of molecules. A radio device receives many signal frequencies at night from broadcasting stations even coming from far countries, while this phenomenon disappears during the daytime. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. If the wavelength of a wave is smaller than the dimensions of the obstacle it faces, it will get reflected by the obstacle. Additionally the larger wavelength of low frequency waves allows them to bend around obstacles more easily than high frequency waves. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Based on the relation between frequency and wavelengths, the higher the frequency, the shorter the wavelengths and therefore the distance of travel is lower.

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. So how would something with less energy travel further? Do low frequencies carry farther than high frequencies? 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.

It does not store any personal data. EDIT: I was thinking about electromagnetic and sound waves when I posted this question. 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 . In fact, sound waves travel over 17 times faster through steel than through air. At any time, day or night, there is a window of usable frequencies created by the reflecting properties of the ionosphere. i) FM is more efficient than AM because the amplitude of an FM wave is constant, irrespective of its modulation index.
