In the case of longitudinal harmonic sound waves, the wavelength can be calculated by the distance the point has traveled from the wave’s source, the ... more

Bernoulli’s equation states that for an incompressible, frictionless fluid, the above mentioned sum is constant. If we follow a small volume of fluid along ... more

The speed of sound is the distance travelled per unit of time by a sound wave propagating through an elastic medium.

The speed of sound is the distance travelled per unit of time by a sound wave propagating through an elastic medium. The speed of sound in seawater depends ... more

Wavelength is the distance between repeating units of a propagating wave of a given frequency.
Wavelength depends on the medium (for example, vacuum, ... more

Acoustic impedance is the measure of the opposition that a system presents to an acoustic flow when an acoustic pressure is applied to it. Acoustic ... more
