For a vibrating string fixed at both ends, what is the relationship between the length of the string and the wavelength when it is vibrating in its second harmonic?
2. For a vibrating string fixed at both ends, vibrating in its third harmonic, how many nodes are there? How many antinodes?
3. Hanging a mass from the end of the string has multiple effects on the system we will be using during the lab: it will affect both the tension, and the mass per length of the string.
(a) When you increase the hanging mass, will the resulting change in the tension cause the frequency to increase, decrease, or stay the same?(b) When you increase the hanging mass, will the resulting change in the mass per length cause the frequency to increase, decrease, or stay the same?
