Hello. A problem I have given my physics class states, "The distance between two crests in a wave is 1.5 m, and two crests pass a pole each second. What is the speed and period of the wave?" I believe the proper solution should be v = 3 m/s, and T = 0.5 s. In order for two crests to pass a given point each second (regardless of initial conditions), it seems that the frequency has to be 2 Hz. However, the solution manual has an answer of v = 1.5 m/s, and T = 1 s (so a frequency of 1 Hz). Could both answers be considered correct due to the wording of the problem?
