Sentence examples for radiation frequency from inspiring English sources

Second, fundamental unit of time, now defined in terms of the radiation frequency at which atoms of the element cesium change from one state to another.

Prior to Bohr, physicists had thought that the radiation frequency would be the same as the electron's frequency of rotation in an orbit.

They are (1) the existence of stationary, nonradiating states and (2) the relationship of radiation frequency to the energy difference between the initial and final states in a transition.

The first condition for the absorption of electromagnetic radiation by a molecule undergoing a transition from a lower energy state, Elo, to a higher energy state, Ehi, is that the frequency of the absorbed radiation must be related to the change in energy by Ehi − Elo = hν, where ν is radiation frequency and h is Planck's constant.

The radiation frequency f m is [4] f_{m}=f_{0} + m Delta f, (4).

Figure 2 Calculated irradiated magnetoresistance versus static magnetic field for a radiation frequency of f = 101 GHz.

The second postulate constituted a significant break from classical electrodynamics, according to which a variety of radiation frequencies would be emitted and those frequencies would be determined solely by the motion of the source.

A high-frequency oscillator provides energy in the form of electromagnetic radiation of frequency ν, with each quantum of radiation having an energy hν, where h is Planck's constant.

The effects of the ionosphere caused by the ionization by solar radiation are frequency dependent and can therefore be considered using two different frequencies.

Conversely, the application of electromagnetic radiation of frequency ν to a molecule in energy state Ehi can result in the emission of additional radiation of frequency ν as the molecule undergoes a transition to state Elo.

: The luminous efficacy Kcd of monochromatic radiation of frequency is exactly 683 lumen per watt (lm·W−1).
