Deriving equation of wave motion

[QUOTE="Bone Rasta, post: 5771943, member: 624323"] I must say that this is the worst derivation of the D'Alambert equation I've ever seen. It's simple but seems to describe any differentiable function. It is true that "wave" is a really general concept, in fact there are many different kind of waves and many different equation describing them, but it's not like [I]anything[/I] is a wave! Anyway, as the text say on page 21, you need at least a second order differential equation to describe a wave since it has in the simplest case an amplitude and a frequency, so two parameters which requires two conditions.
