Traveling Wave Relationship

The relationship of the wave frequency, wavelength and propagation velocity.

This page exists due to the efforts of the following people:


If you throw a rock into a water this will create a wave. The wave would travel outward from the point where the rock hit the water. If propagation velocity is a constant, travelled distance will be velocity multiplied by time. Wavelength is distance travelled by wave for the time equals to wave period.
Thus, to find out wavelength, we need to multiply propagation velocity by period:

\lambda = vT

Using definition of frequency as


we can get standard wave relationship:
