Some articles on waves, wave groups, wave, group:
... For water waves, the nonlinear Schrödinger equation describes the evolution of the envelope of modulated wave groups ... Zakharov describes the Hamiltonian structure of water waves ... In the same paper Zakharov shows, that for slowly modulated wave groups, the wave amplitude satisfies the nonlinear Schrödinger equation, approximately ...
... The interaction of two trains of surface waves of different frequencies and directions generates wave groups ... For wave propagating almost in the same direction, this gives the usual sets of waves that travel at the group speed, which is slower than phase speed of water waves (see animation) ... For typical ocean waves with a period around 10 seconds, this group speed is close to 10 m/s ...
Famous quotes containing the words groups and/or wave:
“As in political revolutions, so in paradigm choicethere is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“And his wish is intimacy,
And a stricter privacy;
The impossible shall yet be done,
And, being two, shall still be one.
As the wave breaks to foam on shelves,
Then runs into a wave again,
So lovers melt their sundered selves,
Yet melted would be twain.”
—Ralph Waldo Emerson (18031882)
