Acoustics

// Concepts

Speed: Is the distance traveled in unit time (m/sg)

Frequency: Number of complete waves in one second. (Hz) The frequency is also called the number of waves that past a point in one second. It can be calculated by dividing cycles of waves with the time the wave takes to be complete.

Wavelength: Distance between matching points in the wave. (m) Is sometimes called Lambda and is measure in meters.

Longitudinal: Vibration parallel to direction of travel. Sound waves are longitudinal.

Transverse: Vibration at right angle to direction of travel. light and radio are transverse waves.//
