closed loop of classical string

zwoodrow

Has anyone seen a treatment of how to use the wave equation to describe a closed loop of string. Im talking ordinary strings here not the fancy string theory kind.

I think its the same as a linear string, except with cyclical boundary conditions?

Actually, there is a good treatment of this in Zwiebach's string theory book. Just check out the earlier chapters, and forget about trying to quantize the string.

Basically, you take the wave equation for a non-closed string, and give it periodic boundary conditions, that's all.
