Introductory Dynamical Oceanography
Wave energy travels at the group speed. One can see this intuitively if one
considers that (in Fig. 12.5) initially at the position x = x2 there is a zero wave
amplitude and therefore zero wave energy, while at x = x, there is maximum
amplitude ...

Ultrasonic tissue characterization II: a collection of ...
The group speed, Cg, is defined also in terms of the wave- number: Cg = dw/dk.
This is the speed that an observer of a "packet" of sound energy, having by
necessity a finite bandwidth, would travel in order to see a constant wave
pressure.

Foundations of Biomedical Ultrasound
The group speed is used to describe the speed with which a representative
characteristic of the pulse moves. Lamb [26, pp. 381-382], has provided a useful
and fairly intuitive definition for the group speed. He noted that the wavelength
could ...

... nondispersive case and 4 s in the dispersive case. In the nondispersive case,
the group speed equals the phase speed of each harmonic wave in the group
and the wave group does not change shape over time as it travels over distance

However, the group-speed dependence on phase speed changes depending on
the nature of the environment – with refraction and reflection-dominated
environments denoting major categories. In reflection-dominated environments,

The speed of propagation of an interference pattern is called its group speed. If
sinusoidal waves of different frequencies possess equal phase speeds, the
interference pattern will propagate at the same speed, so that the group speed
will ...

This means that, given a graph of c(l), we can find the group speed for a
particular wave speed c0 directly from the graph. Here's how we do it: draw the
tangent line to the c (l) graph at the point of interest, namely (c0 (l0), l0) and read
off the ...
