They are not true at the basic level that is the whole point. Mixing up wave, wavelength and frequency and bunch of other concepts illustrate that. This is a forum not a university so I suppose you can still keep going according to the forum rules. For me personally I think it is wrong to post this kind of stuff, other people, young people could read it and think the post is from a source of some authority when it is not. Send them on the wrong path, kids like to browse these sites if they are geeky. A good thing to be in my eyes. I will leave this now to the other guys (second time) for want of committing the act of deceased equine flagellation.
