Sentences with phrase «excited at a particular frequency»

But later the data were reanalysed with algorithms that took into account changes in the mode shapes of the structure — shapes that the structure takes on when excited at a particular frequency.

Not exact matches

The particular interest of this work lies in the fact that by exciting the system at a given frequency — that is, by playing a certain note — the researchers were able to control the behaviour of the membrane at a different frequency, amplifying or suppressing its vibrations depending on the specific excitation conditions.

The frequency at which photons are emitted or absorbed is small relative to the rate of energy redistribution among molecules and their modes, so the fraction of some molecules that are excited in some way is only slightly more or less than the characteristic fraction for that temperature (depending on whether photons absorption to generate that particular state is greater than photon emission from that state or vice versa, which depends on the brightness temperature of the incident radiation relative to the local temperature).
