Talk:Longitudinal wave

message: The patent here is using longitudinal in a much difference sense than the rest of the article. Longitudinal is refering solely to the direction of propagation relative to the bore axis in a putative oil well. So longitudinal means that the wave is moving in the direction of the well axis; not that the electromagnetic waves have vibrations along the axis of propagation. Salsb 21:26, 11 July 2005 (UTC)
replies: text: I agree.  The whole patent section in this article is worthless. Special:Contributions/172.146.167.95 added all of them.  It seems like 172.146.167.95 did a patent search for the term "longitudinal wave" and added all the hits in Wikipedia.  The patent section is not appropriate in this article and I am deleting it. - Ornisong 23:23, 10 November 2007 (UTC)

message: A I correct that (in contrast to transverse waves) the maximum velocity of propagation cannot exceed the individual maximum velocities of the particles transmitting the wave. If this is correct, them em waves in plasma must travel very slowly cf the speed of light. Is that true?--Light current 16:48, 31 July 2006 (UTC)
replies: text: I don't think that is correct, the information between two particles travels at the light speed, and the particle only reacts because of the field it feels. Imagine a wave of cars in a jam, they never go fast, but the wave can go very very fast.Klinfran (talk) 11:08, 28 July 2012 (UTC)

message: Sound waves are simply pressure waves in a fluid and at the correct frequencies so that we can hear them so splitting mechanical longitudinal waves into sound waves and pressure waves is a bit silly. This is shown by the fact that essentially the same equation is included twice. I think those two sections should be merged into a single mechanical longitudinal waves section. anyone object? 137.205.78.240 (talk) 18:58, 23 April 2008 (UTC)

message: With the use of retarded potential, we can easily see there exists a coulombian retarded electric field, and hence a longitudinal electric "wave" but that decays really fast with the distance.Klinfran (talk) 11:05, 28 July 2012 (UTC)
