  2. Natural frequency - Wikipedia

    en.wikipedia.org/wiki/Natural_frequency

    Natural frequency, measured in terms of eigenfrequency, is the rate at which an oscillatory system tends to oscillate in the absence of disturbance. A foundational example pertains to simple harmonic oscillators, such as an idealized spring with no energy loss wherein the system exhibits constant-amplitude oscillations with a constant frequency.

  3. Normal mode - Wikipedia

    en.wikipedia.org/wiki/Normal_mode

    In an electrical dynamical system, a resonant cavity made of thin metal walls, enclosing a hollow space, for a particle accelerator is a pure standing wave system, and thus an example of a mode, in which the hollow space of the cavity is the medium, the RF source (a Klystron or another RF source) is the excitation and the electromagnetic field ...

  4. Mechanical resonance - Wikipedia

    en.wikipedia.org/wiki/Mechanical_resonance

    Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) closer than it does other frequencies. It may cause violent swaying motions and potentially catastrophic failure in ...

  5. Resonance - Wikipedia

    en.wikipedia.org/wiki/Resonance

    Increase of amplitude as damping decreases and frequency approaches resonant frequency of a driven damped simple harmonic oscillator. [1] [2]Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration that matches its resonant frequency, defined as the frequency that generates the maximum amplitude response in the system.

  6. Acoustic resonance - Wikipedia

    en.wikipedia.org/wiki/Acoustic_resonance

    However, if a piece of metal is placed on a prong, the effect dampens, and the excitations become less and less pronounced as resonance isn't achieved as effectively. Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance ...

  7. Harmonic - Wikipedia

    en.wikipedia.org/wiki/Harmonic

    Two different notations of natural harmonics on the cello. First as sounded (more common), then as fingered (easier to sightread). In physics , acoustics , and telecommunications , a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal .

  8. Fundamental frequency - Wikipedia

    en.wikipedia.org/wiki/Fundamental_frequency

    The fundamental frequency, often referred to simply as the fundamental (abbreviated as f 0 or f 1), is defined as the lowest frequency of a periodic waveform. [1] In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present.

  9. String vibration - Wikipedia

    en.wikipedia.org/wiki/String_vibration

    This device allows matching the frequency of the xenon flash lamp to the frequency of vibration of the string. In a dark room, this clearly shows the waveform. Otherwise, one can use bending or, perhaps more easily, by adjusting the machine heads, to obtain the same, or a multiple, of the AC frequency to achieve the same effect. For example, in ...
