The ultrasonic frequency range enabled wholly new kinds of application in medicine and industry.

Medical applications such as ultrasonography and elastography rely on the ultrasonic frequency range.

But if set to a frequency outside the human audible range then the ear can't perceive the square wave, only the difference between the speaker being switched on and off.

Amplifiers may be classified in a variety of ways depending on their application, the frequency range they cover, or the active devices used.

This range is in the globally unlicensed Industrial, Scientific and Medical ( ISM ) 2. 4 GHz short-range radio frequency band.

Bluetooth uses the microwave radio frequency spectrum in the 2. 402 GHz to 2. 480 GHz range.

In radio communications, for example, bandwidth is the frequency range occupied by a modulated carrier wave, whereas in optics it is the width of an individual spectral line or the entire spectral range.

For example, one definition of bandwidth could be the range of frequencies beyond which the frequency function is zero.

In some contexts, the signal bandwidth in hertz refers to the frequency range in which the signal's spectral density is nonzero or above a small threshold value.

Most commonly, bandwidth refers to the 3-dB bandwidth, that is, the frequency range within which the spectral density ( in W / Hz or V < sup > 2 </ sup >/ Hz ) is above half its maximum value ( or the spectral amplitude, in V or V / Hz, is more than 70. 7 % of its maximum ); that is, above − 3 dB relative to the peak.

In calculations of the maximum symbol rate, the Nyquist sampling rate, and maximum bit rate according to the Hartley formula, the bandwidth refers to the frequency range within which the gain is non-zero, or the gain in dB is below a very large value.

This forced development of a variation of DECT, called DECT 6. 0, using a slightly different frequency range ; the technology is nearly identical, but the frequency difference makes the technology incompatible with systems in other areas, even from the same manufacturer.

Radio waves were not detected first from a natural source, but were rather produced deliberately an artificially by the German scientist Heinrich Hertz in 1887, using electrical circuits calculated to produce oscillations in the radio frequency range, following recipies suggested by the equations of James Clerk Maxwell.

As frequency increases into the visible range, photons of EMR have enough energy to change the bond structure of some individual molecules.

Furthermore, religion tends to integrate the whole range of values from the highest or ultimate values of God to the intermediary and subordinate values ; ;

Another example is his very infrequent use of the large amount of data from surveys designed to discover what and how people actually do feel and think on a broad range of topics: he cites such survey-type findings just three times.
