Homework Answers
Answer is (d). Doubling the amplitude of the wave causes the power to be larger by a factor of 4
In (a), halving the linear mass density of the string causes the power to change by a factor of 0.71—> the rate decreases.
In (b), doubling the wavelength of the wave halves the frequency and causes the power to change by a factor of 0.25 —> the rate decreases
In (c), doubling the tension in the string changes the wave speed and causes the power to change by a factor of 1.4 —> not as large as in part(d)

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 frequency of the wave increases its wavelength. Increasing the amplitude of the wave increases its wavelength. 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...

Wave on a String A string with linear mass density 2.0 g/m is stretched along the positive x-axis under a tension of 20 N. The other end of the string, at x = 0m is tied to a hook that oscillates up and down at a frequency of 100Hz with a maximum displacement from equilibrium of 1.0 mm. At t= 0s, the hook is at it's lowest point. (a) What are the wave speed and the wavelength on the string?...
