Hz, is the unit of frequency, and is the number of cycle per second. It is called after a German physicist, Heinrich Hertz. [Pg.113]

Hz = Hertz, unit of frequency - the number of times a wave oscillates per unit time - measured in cycles per second. [Pg.43]

Hertz (Hz) A unit of frequency one cycle per second, 133 Hess, Germain, 207 [Pg.689]

The unit of frequency is the hertz (Hz), which corresponds to one cycle per second. That is, 1 Hz = 1 s . The frequency of a beam of electromagnetic radiation does not change as it passes through different media. [Pg.712]

HERTZ (Hz), A unit of frequency. One hertz equals a frequency of one cycle per second. (The SI unit of frequency.) [Pg.1644]

The SI units of frequency are reciprocal seconds (s ) given the name hertz and the symbol Hz m honor of the nineteenth century physicist Heinrich R Hertz The constant of proportionality h is called Planck s constant and has the value [Pg.520]

Greek letter nu), of the radiation. The unit of frequency, 1 hertz (1 Hz), is defined as 1 cycle per second [Pg.150]

The frequency (represented by v, the Greek letter nu) is the number of waves that pass a given point per second. One hertz (Hz), the SI unit of frequency, equals one wave per second. In calculations, frequency is expressed with units of waves per second, (1/s) or (s ). When expressed in this way, the term waves is understood. For example, 652 Hz = [Pg.137]

F substituent on a molecule Modified enzyme form in ping pong Hz resonance takes place Hertz (unit of frequency cycles per [Pg.801]

The frequency v of a wave is the number of crests passing a fixed point per second. One crest-to-crest oscillation of a wave is called a cycle. The common unit of frequency is the hertz (Hz) or inverse second (s ) an older term for frequency is the cycle per second (cps). One hertz equals one cycle per second. [Pg.66]

HOM2DJ, 2D homonuclear 7-resolved experiment HSC, 2D heteronuclear shift correlation Hz, unit of frequency (cycles per second) [Pg.391]

Henry s law The solubility of a gas in a liquid is proportional to its partial pressure above the liquid solubility X partial pressure. hertz (Hz) The SI unit of frequency 1 Hz is one complete cycle per second 1 Hz = l s 1. [Pg.952]

Other terms used extensively in spectroscopy are the wavenumber and the frequency. The wavenumber is defined as the number of waves per unit of length (usually quoted in units of reciprocal centimetres (cm4 where 1 cm = 10 2 m) and is the reciprocal of the wavelength in centimetres, i.e. HX. The use of wavenumber is usually confined to infrared spectroscopy The frequency is defined as the number of waves emitted from a source per second the unit of frequency is the hertz (Hz 1 Hz = 1 wave per second), and the symbol for it is v (the Greek letter nu ). [Pg.161]

Henry s law The partial pressure of a gas in equilibrium with gas dissolved in a solution is proportional to the concentration of dissolved gas P = Hdissolved gas]. The constant k is called the Henry s law constant. It is a function of the gas, the liquid, and the temperature, hertz. Hz Unit of frequency, s-1. heterogeneous Not uniform throughout. [Pg.693]

Ultrasonic waves are a mechanical disturbance which passes thru the medium by the progressive displacement of particles. The particles do not travel in the direction of the source but vibrate about their mean fixed position. The amplitude of the wave is the distance from peak to peak and therefore is the maximum displacement of a particle in the medium. The period (T) is the time required to complete one cycle and the frequency (f) refers to the number of cycles per unit time. The unit of frequency is the Hertz (Hz, one cycle per second) and it is the reciprocal of the period. The rate at which sound travels thru the medium is the velocity (c, meters per second). The wavelength (X, meters), is the distance between adjacent cycles. Therefore, the relation,between wavelength, velocity and frequency is given by [Pg.46]
