Paul,
I just deleted another of your posts.
They are simply to general to answer. You need to get specific. If you do not have a specific question, then do some searchs (Google, wiki, these forums) on your general topic. (ie waves) If you want a web page on waves then do some searching. Once you have found the general information, learn what you can, come back here with some pointed questions. The more specific your question the better answers you will get.
