  2. Resonance - Wikipedia

    en.wikipedia.org/wiki/Resonance

    Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of, and tension on, a drum membrane. Like mechanical resonance, acoustic resonance can result in catastrophic failure of the object at ...

  3. Electrical resonance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resonance

    Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.

  4. Resonance (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Resonance_(chemistry)

    Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

  5. Acoustic resonance - Wikipedia

    en.wikipedia.org/wiki/Acoustic_resonance

    The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, [1] acoustic resonance can occur at frequencies outside the range of human hearing.

  6. Orbital resonance - Wikipedia

    en.wikipedia.org/wiki/Orbital_resonance

    A Laplace resonance is a three-body resonance with a 1:2:4 orbital period ratio (equivalent to a 4:2:1 ratio of orbits). The term arose because Pierre-Simon Laplace discovered that such a resonance governed the motions of Jupiter's moons Io , Europa , and Ganymede .

  7. Ferroresonance in electricity networks - Wikipedia

    en.wikipedia.org/wiki/Ferroresonance_in...

    Ferroresonance or nonlinear resonance is a rare [1] type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch. [2]

  8. Resonance (sociology) - Wikipedia

    en.wikipedia.org/wiki/Resonance_(sociology)

    Resonance is a quality of human relationships with the world proposed by Hartmut Rosa. Rosa, professor of sociology at the University of Jena , conceptualised resonance theory in Resonanz (2016) to explain social phenomena through a fundamental human impulse towards "resonant" relationships.

  9. Magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance

    Magnetic resonance is a process by which a physical excitation is set up via magnetism. This process was used to develop magnetic resonance imaging (MRI) and nuclear magnetic resonance spectroscopy (NMRS) technology. It is also being used to develop nuclear magnetic resonance quantum computers.
