(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

so the rod is of length l, and the speed of a transverse wave is v_w. It asks for the possible frequencies f_i. The rod is held in the centre so a node exists here.

2. Relevant equations

look below

3. The attempt at a solution

I know that v_w = [tex]\lambda[/tex] * f_i

So it follows that i must find an expression relating wavelength to length. Here is where I run into my problem, it being conceptual. I dont know what occurs at the ends of the rods. I saw a picture somewhere and it appeared to be antinodes but I don't understand why. Could someone give me an explanation?

I would personally think that there could be nodes and antinodes but I'm not sure of this.

Thanks, Redbeard
