20 Hz to 20,000 Hz and they are called Audible Range (Sonic Spectrum).

What is the highest frequency sound that humans can hear?
"Ear". Microsoft Encarta Encyclopedia. CD-ROM. 2000."The maximum range of human hearing includes sound frequencies from about 15 to about 18,000 waves, or cycles, per second."15-18,000 Hz
What part of the electromagnetic spectrum usually used for communication is?
Roughly the range of frequencies between 50 KHz and 100 GHz, give or take an octave.
What is the relationship between frequency amplitude and pitch?
Wavelength = (speed of sound) divided by (frequency) Frequency = (speed of sound) divided by (wavelength) Amplitude is not related to frequency or wavelength. A change of amplitude does not cause ... and does not result from ... a change of frequency or wavelength
What wave has the hightest frequency?
Did you mean to give us choices? As far as I know there is no absolute maximum frequency - it approaches infinity for very short wavelengths. I guess the answer would be "the wave with the shortest wavelength has the highest frequency"
What is the frequency of light in fused quartz if the wavelength in vacuum is 500nm?
Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.
Give an example of cummulative frequency curve?
Cumulative frequency is the running total of frequencies. It can be shown on a graph by joining points. For example if frequencies are 4, 6, 3, 2, 6, 10 then their cumulative frequencies are 4, 10, 13, 15, 21 and 31 respectively.
Give the difference between LPF and HPF?
LPF is a low pass LTI filter which passes the low frequency signals and reduce the amplitude of the signals with frequencies higher than the cutoff frequency. HPF is high pass LTI filter which passes the high frequencies and reduce the amplitude of the frequencies lower than filter's cutoff frequency.
What is the frequency of a hydrogen atom?
An atom doesn't have a frequency. It can vibrate with many different frequencies. It can absorb radiation of different frequencies under different circumstances. For instance, electrons moving between various energy levels absorb and release characteristic frequencies of visible and ultra-violet light, and in a magnetic field radio frequency energy can be absorbed as the nucleus moves from one spin state to another. Bonds between hydrogen and other atoms absorb energies in the infra red. All these things give spectra of various frequencies, not an individual frequency.
What is a 7 band Equalizer?
A 7 band equaliser is a device that has 7 separate frequency range sliders, were the frequency is centered on the frequency stated below the slider. When a note is played it is made up of a series of frequencies, the fundamental being the one you hear and then a series of harmonics or overtones. A slider will then increase or decrease the 'intensity' of the overtones within its frequency range, depending on the position of the slider. Most sliders can increase or decrease the intensity of a certain overtone by up to 12 or 15dB. The use is to make a note or music played sound of higher or bassier sound, if you have one push the sliders on the left up and you get a real 'thuddy' bass sound and the ones on the right give you a real 'tinny' high pitched sound. A typical guitar EQ will have sliders centered on say 100, 200, 400, 800, 1600, 3200 and 6400Hz. The reason for the larger gap between the frequency sliders as the frequency increases is due to the ears response to sound, (The ear can distinguish between different frequencies better at low frequencies).

Can you give the frequency for all radio stations?
Yes we can. At least for the commercial broadcast stations in the USA.AM stations:Carrier frequencies are at every 10 KHz, between 550 KHz and 1700 KHz.FM stations:Carrier frequencies are at every 0.2 MHz, between 88.1 MHz and 107.9 MHz.
Does a magnetron give off radio waves?
A magnetron may be used to generate radio-frequency currents and fields at high power and high frequencies. The source of RF in most microwave ovens is a magnetron.
What are advantages you have of frequency domain analysis over time analysis?
Frequency Analysis is much easier. Some equations can't be solved in time domain while they can be solved easily in frequency domain. When moving to frequency domain you change the differential equation into algebric equation. Also, in frequency domain it is easy to apply filters and compute their specifications. In telecommunications, using multiple frequencies enables more than one user to use the service at the same time if having different frequency, this enables less delay for the signal. Also, it would be easier, when using frequency domain- to give each user, or each standard (GSM, Satellite ...) it's own frequency range without interfering. This can't be done in time domain
What is the overtone series?
The overtone series is a series of frequencies that are integer multiples of the fundamental frequency of a sound. When a musical instrument produces a note, it actually produces a complex waveform that includes the fundamental frequency and various overtones. These overtones give each instrument its unique tone color or timbre.
What is a cumulative frequency histogram?
-Construct a frequency table-Draw a horizontal axis and mark off the intervals.Label the horizontal axis.If the first interval does not start at 0, use a "break" symbol on the axis.-Draw a vertical axis and identify a scale for the frequencies. Label the vertical axis.Often, the vertical axis is "frequency".-Draw bars with heights corresponding to the frequency values in the table.-Give the graph an appropriate title.
What part of the electromagnetic spectrum usually used for communication is?
Roughly the range of frequencies between 50 KHz and 100 GHz, give or take an octave.
Why isn't used radio wave for satellit but use the micro wave?
"Microwave" is just the name we give to radio waves with wavelengths less than 10 cm (frequencies above 3 GHz). So you're really asking why frequencies/wavelengths in that region are used for satellite communication. -- The higher frequency/shorter wavelength is selected, the more information can be carried on a single signal. -- The higher frequency/shorter wavelength is selected, the more effectively the signal can be focused and beamed in the desired direction by the design of the antenna. -- But if you use frequencies too high / wavelengths too short, then the signal is absorbed moderately by atmospheric gases, and heavily by rain/snow/fog. So the 'sweet' range for satellite operation falls roughly in the range of perhaps 1 - 100 GHz / 1 mm - 30 cm .
