40 types ???[edit]

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) Alex is gay[reply]

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

we?[edit]

"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)[reply]

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

More than 3 types...[edit]

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)[reply]

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)[edit]

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)[reply]

Speed of transverse waves[edit]

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)[reply]
