Homework Help: Physics please help me

Posted by Anonymous on Wednesday, December 12, 2012 at 11:36pm.

Two identical guitar strings are stretched with the same tension between supports that are not the same distance apart. The fundamental frequency of the higher-pitched string is 400Hz, and the speed of transverse waves in both wires is 200 m/s. How much longer is the lower-pitched string if the beat frequency is 4Hz?
