Fast/slow Alfven waves in High/Low Beta Plasma?

[Alita1984]

Guys can you please tell me how fast/slow Alfven waves propogate in High/Low Beta Plasma? I need to derive equation cannot find any clue on that! Please be so kind to help me please!

MHD wave theory borders on crackpot.

Crackpot? That's news to me. Alfven won the Nobel Prize. Aren't Alfven waves just sound waves in a plasma?

It is true that Alfven came up with a cosmological theory that turned out to be wrong and that crackpots have latched onto it, but Alfven can't be blamed for that.

You can find the general theory of plasma waves in hot (or cold) plasmas (any beta) in this chapter:

In principle, you can identify the cold limit and the Alfven wave and see how it transform in hot plasmas.

See also the cold text:

The reference above is rather lengthy, you may find similar material in a more compact presentation, with google.
My preferred reference on plasma electrodynamics is:

Principles of plasma electrodynamics, Springer

A more specialized book on Alfven waves might help you too:
