331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.
It is called the frequency. The SI unit is the Hertz. One Hertz is one cycle per second.
Hertz (Hz) is the SI unit of frequency, equal to one cycle per second.
Frequency is measured in hertz. Cycles per second.
dynamic frequency, which is cycles per second, or Hertz
That is possibly the input impedance of a loudspeaker - not an impedance of an amplifier.
A second is a length of time, while a hertz is a unit of frequency, so you can have as many hertz in a second as you want. therefore it depends on what frequency you are talking about, as you can have hundreds of thousands of hertz per second.
Frequency, which is measured in Hertz (Hz)
The hertz (symbol Hz) is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon
Hertz means cycles per second. That is its' frequency.
The SI unit for frequency is Hertz, the number of cycles per second.
Hertz, hz= 1/second is the unit measure of frequency.
It is a frequency of 12 Hertz.
It's "hertz", not "hetz". The number of hertz is the frequency. For example, if the current has a frequency of 50 hertz... well, that's the frequency. Hertz is equivalent to cycles/second, and it is sometimes written that way. So, 50 hertz could also be written as 50 cycles/second.
Frequency is measured in Hertz, not metres per second.
