Relationship between frequency and

Using the relationship between frequency and wave number, we have ... 

The quartz crystal microbalance (QCM) is a piezoelectric device consisting of a thin (e.g.) quartz wafer sandwiched between two electrodes. A potential applied across the electrodes results in an oscillation of the quartz. The frequency of the oscillation, which can be measured accurately, is sensitive to mass loading. The relationship between frequency and mass loading is described by the Sauerbray equation ...

While for some purposes it may be necessary to have accurate frequency definition, for others good time discrimination is useful. These are opposite requirements. Because of the Fourier relationship between frequency and time, the more precisely the time of a signal is known, the greater bandwidth of frequencies is necessary (there is a close analogy here with Heisenberg s uncertainty principle). Approximately, the time resolution t is the reciprocal of the bandwidth Bw, so that their product Bwr 1. 

Where h = Planck s constant (6.6208 x 10 34Js) and v = frequency in inverse seconds. Next, the relationship between frequency and wavelength is described as ... 

STATISTICAL NATURE OF TURBULENCE. The distribution of deviating velocities at a single point reveals that the value of the velocity is related to the frequency of occurrence of that value and that the relationship between frequency and value is gaussian and therefore follows the error curve characteristic of completely random statistical quantities. This result establishes turbulence as a statistical phenomenon, and the most successful treatments of turbulence have been based upon its statistical nature. ... 

Risk needs to be considered in the context of the individual and that of a society (or population). Individual risk is the frequency at which an individual may be expected to sustain a given level of harm from the realization of specified hazards and, societal risk is the relationship between frequency and the number of people suffering from a specified level of harm in a given population from the realization of specified hazards . 

The relationship between frequency and density, expressed in Equation (5), is obtained from Equations (2) and (4).

The relationship between frequency and is often expressed in terms of the empirical Vogel-Fulcher-Tammaim law (often just called the Vogel-Fulcher law, usually encountered in discussion of the viscous flow of amorphous liquids and glasses) and expressed for relaxors as...

For these inclusion compounds where the cavity has a three-fold symmetry axis the normal coordinates are symmetry-determined and it becomes possible to analyse the temperature-dependence of the NQR frequencies completely. The practical difficulty is that the theoretical relationship between frequency and temperature applies to constant volume conditions [10,11] while the experimental data are usually obtained at constant pressure. 

Individual risk is simply the predicted frequency of the undesired outcome. Societal risk takes account of both the severity of the range of possible outcomes and the frequency at which they each are predicted to occur. It is usually presented as a two-dimensional relationship between frequency and cumulative severity of outcome, called an F-N curve. The F-N curve is frequently used for giving target values for maximal numbers of accidents (say F) with N or more accidents. The F-N...
