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?...

Cousin Throcky holds one end of the string and wiggles it up and
down sinusoidally with frequency 2.00 Hz and amplitude 0.075 m. The
wave speed on the string is 12 m/s. At t = 0 s, Throcky’s end has
maximum positive displacement and is instantaneously at rest.
Assume the wave travels to the right and no wave bounces back from
the far end.
