Ive been trying this problem for awhile now and I seem to not get it. A hand holding a rope moves up and down to create a transverse wave on the rope. The hand completes an oscillation in 2.5s, and the wave travels along the string at 0.8 m/s. The amplitude of the wave is 0.1m. The frequency at which the crests pass a given point in space is 0.4 Hz. The distance between the two adjacent crests on the wave is 2m. a) There is a blue spot drawn onto the rope with a magic marker. Find the distance this spot travels in one period. I have tried using the equation y(t)=Asin(2*pi*f*t) which is 0.1m*sin(2*pi*.4*2.5) = .0109 m and I got this wrong. I am not sure where I did go wrong and was wondering if anyone can help me. Thanks.
