Question

(e) Of the points A, B, C, and D on the uppermost graph, which one could be represented by the lower graph?

Assume that the wave is propagating to the right and that the upper picture shows the segment at time t= 0

seconds.

(circle one) A B C D

wave is propagating to the right along a string. The first picture above shows a snapshot of a segment of the string at time, t=0. The second picture above is a graph of the vertical displacement of a point along picture the string as a function of time (e) Of the points A, B, C, and D on the uppermost graph, which one could be represented by the lower graph? Assume that the wave is propagating to the right and that the upper picture shows the segment at time t= 0 seconds. (circle one) A B C D

Explanation / Answer

According to second plot - At time t=0 , vertical displacement = 0 , Hence the possible solutions are (A and C).

Given that the wave moves towards the right (and velocity at t=0 is negetive)- Hence the solution is point is C
