Talk:Mechanical wave

40 types ???
What are the 40 types of mechanical wave ? The article shoud have a reference about this statement and a list of the 40 types should be included. —Preceding unsigned comment added by 70.55.183.10 (talk) 23:29, 3 June 2008 (UTC)


 * There's 3 types of mechanical waves, not 40. 2CrudeDudes (talk) 16:24, 17 February 2011 (UTC)

we?
"There are 40 types of mechanical waves; we have listed 3." Is this copied from somewhere? —Preceding unsigned comment added by 66.76.60.154 (talk) 04:29, 30 January 2009 (UTC)


 * It was wrong, but its fixed now. This article still needs a lot of help though. 2CrudeDudes (talk) 16:25, 17 February 2011 (UTC)

More than 3 types...
There are actually more than 3 types of acoustic wave (and thus mechanical wave); see this page for example... Sanchonx (talk) 17:43, 28 February 2011 (UTC)

I agree that there is more than 3 types but these are the basic ones you learn in 9th grade physical science. (cgreen)

SURFACE WAVES (circular wave fronts)
Does anyone know what is meant when the author states, "surface waves(travels in clockwise circles)."? I believe it should be noted that a surface wave is merely a transverse wave that moves radial outward from a central point. (kglynn)

Yes, this really ought to be changed AS ABOVE is correct. — Preceding unsigned comment added by 123.211.175.209 (talk) 12:05, 14 June 2012 (UTC)

Speed of transverse waves
Do transverse waves generally travel more slowly than longitudinal waves? Seismic waves says so. For a variety of materials, the article says. But are they all seismic materials? 129.132.211.13 (talk) 21:33, 15 February 2015 (UTC)
