Hertz is a unit to measure frequency. Number of waves passing through a particular point in unit time is considered to define frequency. The unit for frequency is inverse seconds.
That depends on the type of siren. If you mean a Q then there is no set frequency.
If by greatest frequency you mean highest frequency, we know that the upper end of the electromagnetic spectrum has the greatest frequency. This is the home to the gamma rays. They have the highest frequency, shortest wavelength, and the greatest energy.
Energy. (if you mean E=h*ni) If you're referring to sound then the greater the frequency the smaller the wave length. (v=lambda*f)
increasing wavelength means shorter frequency.
If you mean the pitch of a sound, that is related to its frequency. The SI unit is the Hertz.
Most dynamic microphones have a response from about 15Hz to 15 kHz, although they differ widely depending upon model.
The frequency units are called hertz (Hz). Sounds between 20 Hz and 20,000 Hz can be heard by those with normal hearing. Ultrasound is defined as frequencies greater than 20,000 Hz.
Most dynamic microphones have a response from about 15Hz to 15 kHz, although they differ widely depending upon model.
HIGHEST AUDIBLE FREQUENCY IS 25Hz..WHILE THE LOWEST AUDIBLE FREQUENCY IS 15Hz
A 20Hz signal must be sampled at a minimum of 40Hz to have a chance of sampling both peaks and to get a reasonable representation it must be sampled at a minimum of 100Hz.For a sampling rate of 30Hz the Nyquist frequency is 15Hz and since 20Hz is above that it will generate the alias signal of 10Hz in the sampled data instead of the original signal of 20Hz. Therefore it is not possible to do what you ask.
Frequency is how often something happens.
Frequency is rate of an occurence. Polling is asking for an answer. Frequency polling is checking for an answer on a set schedule.
That depends on the type of siren. If you mean a Q then there is no set frequency.
Cumulative Frequency
Does what hurt? Do you mean sound?
literally, 'to frequency'..
Very high frequency
