A vertical, 1.30-m length of 18-gauge (diameter of 1.024 mm) copper wire has a 160.0-N ball hanging from it.
Part A What is the wavelength of the third harmonic for this wire?
Part B A 800.0-N ball now replaces the original ball. What is the change in the wavelength of the third harmonic caused by replacing the light ball with the heavy one? (Hint: See Table 11.1 in the textbook for Young's modulus.)
