Wave velocity

From Wikipedia, the free encyclopedia

Wave velocity is a general concept, of various kinds of wave velocities, for an electromagnetic wave's phase and speed concerning energy (and information) propagation. The relationship between group velocity and phase velocity is the dispersion relationship.

[edit] Explanation

In almost all cases, A wave is merely a movement of energy through a medium.

Wave velocity is the speed at which the energy moves through this medium. The more dense a medium is, the faster the waves will travel as particles will be closer together and thus energy can be transferred among them at a greater rate.

The universal wave equation is:

where

v is the wave velocity ([LT ⁻¹]; m/s);

λ is the wavelength ([L]; m);

f is the frequency ([T ⁻¹]; Hz or ¹⁄_s); and,

T is the period ([T]; s).
