## Inaccuracy?

"There are two types of wave propagation: longitudinal and transverse. An example of the former is the guitar string, which creates sound waves."

This strikes me as incorrect; I thought the vibration of a guitar string is a transverse wave (the resultant sound waves are longitudinal, though). Powers T 19:12, 21 November 2006 (UTC)

You're right. The way the wave is propogated is by a transverse vibration. The wave itself is longitudinal. I'll fix it. 72.1.206.174 16:49, 2 May 2007 (UTC)

## Requires Good Amount Of Cleaning Up

This article needs some major cleanup. It doesn't explain the idea of nodes/antinodes well, nor how they are formed. It does not talk about how the nodes relate to the natural frequency of an object, nor interference patterns. There should also be information pertaining to the superposition principle, and the resonant lengths. I could go on and on. Work on this article please!! 72.1.206.174 16:53, 2 May 2007 (UTC)

## Another inaccuracy?

"In transmission lines a voltage node is a current antinode, and a voltage antinode is a current node."

Wouldn't this depend upon the complex impedance of the line? —Preceding unsigned comment added by Bgamari (talkcontribs) 06:31, 30 November 2009 (UTC)

## Midway?

The article currently asserts that antinodes occur "midway" between nodes, which I interpret to be exactly halfway between them. But this assertion seems intuitively true only for symmetric waves. In fact, I think that I can construct a counterexample to this claim. 99.76.14.134 (talk) 07:51, 3 January 2014 (UTC)
