A 200 g mass is hanging from a long string draped over a pulley and attached to a fixed frequency generator which can operate in the range 60 – 120 Hz. The mass per unit length of the string is 1.51 g/m.
The length of string between the frequency generator and the pulley is 90 cm.
a) Which frequencies of the generator will result in standing waves on the string?
b) Sketch each standing wave and list the mode (harmonic number).

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...

A string of length L = 1.2 m is attached at one end to a wave oscillator, which is vibrating at a frequency f = 80 Hz. The other end of the string is attached to a mass hanging over a pulley as shown in the diagram below. When a particular hanging mass is suspended from the string, a standing wave with two segments is formed. When the weight is reduced by 2.2 kg, a standing wave with five segments...

With the string stretched by hanging a mass of 200.0 +0.1 g over the pulley, a frequency generator creates a vibration in the string and the frequency for resonances are recorded for each case of an integer number of anti-nodes from 1 to 7. The frequency is plotted as a function of the integer number anti-nodes and a linear trend line fit is made of the plotted data. The slope of the trend line fit for the graph is m...

In the standing waves experiment, the string has a mass of 44.5 g string and length of 1.18 m. The string is connected to a mechanical wave generator that produce standing waves with frequency of f. The other end of the string is connected to a mass holder (mholder = 50.0 g) that carries a weight of 5.00x102 g. Calculate the the frequency of the mechanical wave generator f, if the number of antinodes was 2. (g = 9.80 m/s2)
