It just is. Sound behaves like a wave, and the pitch of the sound affects the wavelength. And wavelength is directly related to the frequency. A high pitched sound has a a shorter wavelength and a higher frequency than a low-pitched sound.
50 hertz
hertz is what frequency waves are measured in.
dynamic frequency, which is cycles per second, or Hertz
Hertz, hz= 1/second is the unit measure of frequency.
Frequency is the amount of times a wave passes through an area. Hertz is a measurement.
50 hertz
Frequency is measured in Hertz. Its symbol is Hz.
hertz is what frequency waves are measured in.
dynamic frequency, which is cycles per second, or Hertz
Frequency is measured in hertz. Cycles per second.
hertz Hz
it is named after the scientist hertz
Hertz means cycles per second. That is its' frequency.
Frequency, which is measured in Hertz (Hz)
A wave can have any frequency, not just one Hertz.
Hertz. Hz
It depends on the individual whistle. The typical dog whistle has a range of 16,000 to 22,000 hertz. If one is 22,000 hertz, a human will barely be able to detect it, but it won't be a problem for a dog.
