A hand holding a rope moves up and down to create a transverse wave on the rope. The hand completes an oscillation in 1.4 s, and the wave travels along the string at 0.6 m/s. The amplitude of the wave is 0.1 m. The frequency at which the crests pass a given point in space is 0.7143 Hz. The distance between two adjacent crests on the wave is 0.84 m. a. There is a blue spot drawn onto the rope with a magic marker. Find the distance thsi spot travels in one period. b. If the mass per unit length of the string is 6 x 10-4 kg/m, what is the tension in the string? For part a, I tried velocity/time, using both 0.6 and 0.84 as my answers, and both were wrong. I have a feeling part b depends on part a, so I will wait off on part b.
