The speed of a wave in a string is given by v = sqrt(FT/μ), where FT is the tension in the string and μ = mass/length of the string.

A 2.00 m long string has a mass of 16.5 g. A 769 g mass is attached to the string and hung over a pulley . The end of the string is then vibrated at a frequency of 129 Hz. Find the wavelength for the wave generated. Give your answer in centimeters (cm) and with 3 significant figures.

A standing wave pattern is created on a string with mass density μ = 3 × 10-4 kg/m. A wave generator with frequency f = 63 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 = 0.68 m. Initially the 3rd harmonic wave pattern is formed....

10. [1pt] Consider a transverse harmonic wave travelling along a string. Enter true (T) or false (F) for the following statements. For example, if the first statement is true and the rest false, enter TFF. You have 4 tries. Increasing the amplitude of the wave increases its frequency. If a wave with a frequency of 10 Hz travels along a string with a mass per unit length of 40 g/m stretched to a tension of 100 N, its wavelength is...
