Sound - Circular and spherical waves | Britannica

    Sound - Sound - Circular and spherical waves: The above discussion of the propagation of sound waves begins with a simplifying assumption that the wave exists as a plane wave. In most real cases, however, a wave originating at some source does not move in a straight line but expands in a series of spherical wavefronts. The fundamental mechanism for this propagation is known as Huygens ...

    Vibrational Modes of Drums - The Physics of Sound

    The third main mode of vibration of a circular membrane is the (2,1) mode. This is the second most important vibrational mode in terms of the musical quality of the drum. The (2,1) mode vibrates at a frequency 2.135 times the frequency of the (0,1) mode. The nodal point run the diameter of the drum at right angles to each other, making a large X.

    Forced Vibrations & Resonance - Physics

    Free vibrations are oscillations where the total energy stays the same over time.This means that the amplitude of the vibration stays the same. This is a theoretical idea because in real systems the energy is dissipated to the surroundings over time and the amplitude decays away to zero, this dissipation of energy is called damping..

    Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion. A body in periodic motion is said to have undergone one cycle or one vibration after passing through a series of events or positions and returning to its original state.

    A fundamental vibration mode will be infrared active only if the its symmetry belongs to the same representation as any one or several of the Cartesian axes. For example, a totally symmetric mode cannot be infrared active since the dipole moment remains unchanged during the vibration.
