The Wave Equation

Wave speed is defined as:

“The distance travelled by a wave each second”

Wave speed is given the symbol v and is measured in metres per second (m/s)

Wave speed is the speed at which energy is transferred through a medium

Transverse and longitudinal waves both obey the wave equation:

WAVE SPEED = FREQUENCY X WAVELENGTH

v=fv = f x 𝜆𝜆

Where:

  • v = wave speed in metres per second (m/s)

  • f = frequency in Hertz (Hz)

  • 𝜆 = wavelength in metres (m)
