For bass instruments, higher-power amplifiers are needed to reproduce low-frequency sounds.

Such devices are very convenient in the manufacture of voltage-controlled oscillators For low-frequency VCOs, other methods of varying the frequency ( such as altering the charging rate of a capacitor by means of a voltage controlled current source ) are used.

For those concerned with low-frequency electromagnetic radiation in the home, the following conversions are needed most:

For some cases low-frequency AC is used, and distributed by a special traction current network.

For this purpose, phasers usually include a low-frequency oscillator.

For a large ensemble of randomly oriented spins, the EPR spectrum consists three peaks of characteristic shape at frequencies g < sub > xx </ sub > B < sub > 0 </ sub >, g < sub > yy </ sub > B < sub > 0 </ sub > and g < sub > zz </ sub > B < sub > 0 </ sub >: the low-frequency peak is positive in first-derivative spectra, the high-frequency peak is negative, and the central peak is bipolar.

For the case of Jupiter, the radio emission spectrum is definitely not like the spectrum of a black-body radiator, and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non-thermal components.

For irradiation of food, the results obtained depend upon the dose rather than the specific type of radiation, and X-ray, gamma, and high-energy electron radiation are suitable.

For example, a lamp that emits 590 cd with a radiation angle of 40 ° emits about 223 lumens.

* For some reactions, the presence of electromagnetic radiation, most notably ultraviolet light, is needed to promote the breaking of bonds to start the reaction.

For lower frequencies of EMR up to those of visible light ( i. e., radio, microwave, infrared ), the damage done to cells and also to many ordinary materials under such conditions is determined mainly by heating effects, and thus by the radiation power.

For example, when electromagnetic radiation is absorbed by matter, particle-like properties will be more obvious when the average number of photons in the cube of the relevant wavelength is much smaller than 1.

For this reason, infrared, microwaves, and radio waves are thought to damage molecules and biological tissue only by bulk heating, not excitation from single photons of the radiation ( however, there does remain controversy about possible non-thermal biological damage from low frequency EM radiation, see below ).

For these thermal effects, the frequency of the radiation is important only as it affects radiation penetration into the organism ( for example microwaves penetrate better than infrared ).

For instance, when atoms are irradiated by a source with a broad spectrum, distinct absorption lines will appear in the spectrum of transmitted radiation.

For example, a system can emit energy to another by transferring ( radiating ) electromagnetic energy, but this creates forces upon the particles that absorb the radiation.

For other actions ( such as determining the result of radiation exposure ), the matrix result indicates a non-negotiable result.

For efficient detection of alpha particles the GM tube window should ideally be within 10mm of the radiation source due to the attenuation in free air.

For high energy gamma, this relies on interaction of the photon radiation with the tube wall material, usually 1-2mm of chrome steel to produce electrons which can enter and ionise the fill gas.

For example, an explosion is the result of a chain reaction that transforms potential energy stored in chemical, mechanical, or nuclear form into kinetic energy, acoustic energy, and electromagnetic radiation.

For the density of the observable universe of about 4. 6 × 10 < sup >− 28 </ sup > kg / m < sup > 3 </ sup > and given the known abundance of the chemical elements, the corresponding maximal radiation energy density of 9. 2 × 10 < sup >− 31 </ sup > kg / m < sup > 3 </ sup >, i. e. temperature 3. 2K.

For a given metal, there exists a certain minimum frequency of incident radiation below which no photoelectrons are emitted.

For a given metal and frequency of incident radiation, the rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light.

For example, an increase in frequency results in an increase in the maximum kinetic energy calculated for an electron upon liberation – ultraviolet radiation would require a higher applied stopping potential to stop current in a phototube than blue light.

For 10 years Sponsor has issued an annual survey of the size and characteristics of the Negro market and of successful techniques for reaching this market through radio.

For many years he simultaneously produced the daily strip, a weekly syndicated newspaper column, and a 500-station radio program ...." He ran the Boston Summer Theatre with The Phantom cartoonist Lee Falk, bringing in Hollywood actors such as Mae West, Melvyn Douglas and Claude Rains to star in their live productions.

For example, an FM radio receiver's tuner spans a limited range of frequencies.

For example, the introduction of FM stereo transmission allowed backward compatibility since new FM radio receivers could receive monaural signals generated by old transmitters.

For foreign news, first a " generic minute " is recorded, then reports are to World Service radio, then the reporter talks to any other programmes that are on air.

For example, diodes are used to regulate voltage ( Zener diodes ), to protect circuits from high voltage surges ( avalanche diodes ), to electronically tune radio and TV receivers ( varactor diodes ), to generate radio frequency oscillations ( tunnel diodes, Gunn diodes, IMPATT diodes ), and to produce light ( light emitting diodes ).

For example, the Kothmale Community Radio Internet uses both radio broadcasts and computer and Internet technologies to facilitate the sharing of information and provide educational opportunities in a rural community in Sri Lanka.

For instance, the metal atoms in a radio transmitter appear to transfer energy continuously.

For example, if an office has two telephone operators who are both busy all the time, that would represent two erlangs ( 2 E ) of traffic ; or a radio channel that is occupied for one hour continuously is said to have a load of 1 Erlang.

For his wartime work on radio the French government gave him the Legion of Honor in 1919.

Records such as " Let Me Be the One " by Safire, " I Remember What You Like " by Jenny Burton, " Running " by Information Society, " Give Me Tonight " by Shannon and " It Works For Me " by Pam Russo enjoyed heavy New York radio airplay.

For example, narrowband FM is used for two way radio systems such as Family Radio Service, in which the carrier is allowed to deviate only 2. 5 kHz above and below the center frequency with speech signals of no more than 3. 5 kHz bandwidth.

For example, many workers listen to the radio through the Internet while sitting at their desk.

For 37 years beginning in 1967, Albert was the voice of the New York Knicks on radio and television ( getting his start by being a ball boy for the Knicks before getting his first break on New York radio by sportscaster Marty Glickman ) before being let go by the chairman of the MSG Network and Cablevision after Albert criticized the Knicks ' poor play on-air in 2004.

For many years, many listeners have been dissatisfied with the content of radio programming since the decline of early free form rock radio.

For whatever reason, there seem to have been no attempts for 30 years, until Jansky's development of radio astronomy in 1932.

For the rest of the decade Limbaugh took jobs at several radio stations, working in music radio, before settling in Kansas City.
