A 4.5-Hz wave with an amplitude of 12 cm and a wavelength of 27 cm travels along a stretched horizontal string. (a) How far does a given peak on the wave travel in a time interval of 0.50 s? (b) How far does a knot on the string travel in the same time interval? (c) How would your answers to parts (a) and (b) change if the amplitude of the wave were halved? Explain.
