Everything about Wave Velocity totally explained
Wave propagation is any of the ways in which
waves travel through a
medium (
waveguide).
With respect to the direction of the
oscillation relative to the propagation direction, we can distinguish between
longitudinal wave and
transverse waves.
Another useful parameter for describing the propagation is the
wave velocity that mostly depends on some kind of
density of the medium.
For
electromagnetic waves, propagation may occur in a vacuum as well as in a material medium.
Wave velocity
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:
»
where
» is the wave velocity ([LT
−1]; m/s);
is the wavelength ([L]; m);
» is the
frequency ([T
−1];
Hz or );
is the period ([T]; s);
» is the
angular frequency (rad Hz or ); and,
is the wavenumber .
