You have a string with a mass of 12.9 g. You stretch the string with a force of 9.19 N, giving it a length of 1.95 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic. What is the wavelength of the standing wave you create in the string? What is the frequency?

You have a string with a mass of 0.0139 kg. You stretch the string with a force of 9.59 N, giving it a length of 1.85 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic. What is the wavelength of the standing wave you create in the string? What is the frequency?
You haw a uniform string with a mass of 0.0130 kg and length 1.75 m under a tension 10.0 N. The string is fixed at both ends, and is vibrating at its fourth resonant frequency (i.e. the fourth harmonic). What is the wavelength of the standing wave in the string? What is the frequency?
Problem 2 [8 pts] Oscillator As a quality control technician at a violin string factory, you cut a sample of E-string off a large roll. The sample that you cut has a mass of ms = 1.021 grams and a full length of 2.5 meters. To test the string, you stretch some of it across a length L = 0.35 m, applying tension by means of a hanging mass m (as pictured). A variable frequency oscillator is used to excite...

A standing wave pattern is created on a string with mass density u- 3x 10 kg/m. A wave generator with frequency f- 65 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L- 0.74 m. Initially the 3rd harmonic wave pattern is formed. What is the wavelength...
