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 460Hz, and the speed of transverse waves in both wires is 150 m/s. How much longer is the lower-pitched string if the beat frequency is 6Hz?

Standing waves are set up on two strings fixed at each end, as shown in the drawing. The two strings have the same tension and mass per unit length, but they differ in length by 0.51 cm. The waves on the shorter string propagate with a speed of 42.6 m/s, and the fundamental frequency of the shorter string is 232 Hz. Determine the beat frequency produced by the two standing waves.
