Question

The diagram below shows the peaks of a traveling circular wave. The first peak that the source produced is shown in light green, the second in dark green, and the third is just about to be produced at the point in the center. Observer A stands to the right of the source, and observer R stands to the left. The grey lines are simply guidelines and do not represent anything physical. 1. This circular wave has a wavelength of λ. On the diagram, mark a distance corresponding to . 2. This circular wave has a period of T. If the first peak was produced at t = 0, then at what time, in terms of T, was the above snapshot taken? 3. What is the speed of the wave (v), in terms of previously-defined quantities?
