Higher frequency shorter range
Web15 de nov. de 2015 · A decent approximation for the maximum attenuation of sound waves between 50 kHz and 300 kHz is α (f) = 0.022 * f – 0.6 1, where α (f) is the maximum attenuation in dB/ft, and f is the frequency … Web20 de mar. de 2024 · FM uses a higher frequency range and a bigger bandwidth than AM. AM radio operates from 535 kHz (kiloHertz) to 1605 kHz. When you tune the dial on your radio, the number changes by 10 kHz each time. This means that each station has 10 kHz of bandwidth on which to broadcast.

In linear media, any wave pattern can be described in terms of the independent propagation of sinusoidal components. The wavelength λ of a sinusoidal waveform traveling at constant speed is given by =, where is called the phase speed (magnitude of the phase velocity) of the wave and is the wave's frequency.In a …
WebMore intuitively, the theorem says that it's impossible to have a very short note with a clearly defined pitch. If you try to play a central A, at 440 Hz, for less than, say, 10 milliseconds, then you won't have enough periods to really lock in on the frequency, and what you hear is a broader range of notes.
