Not what you're looking for?

Problem 21.10
Part A
What are the three longest wavelengths for standing waves on a 171- -long string that is fixed at both ends?

Part B
If the frequency of the second-longest wavelength is 59 , what is the frequency of the third-longest wavelength?

Problem 21.39
A guitar string with a linear density of 2.00 is stretched between supports that are 60.0 apart. The string is observed to form a standing wave with three antinodes when driven at a frequency of 440 .
