1. The problem statement, all variables and given/known data A beach comber walking along the top of a sea wall notices that the waves reflecting off of the concrete breaker are creating a pattern of interference with the original incoming waves. A few meters from the breaker the waves are at maximum oscillation with a time between peak and trough of 2.4 seconds. Exactly 3.2m further to sea, there is virtually no vertical change in the water's motion. What is the length and velocity of the waves? 2. Relevant equations v=fxlamda 3. The attempt at a solution So I'm not sure if I'm completely misinterpreting this but I'm thinking it forms a standing wave pattern and the first node is 3.2m away from the antinode so 3.2m x 4 = a wavelength of 12.8m and then v=(4.)(12.8m)(1/4.8)= 2.7m/s Did I do it right or am I completely off?
