2. Two point sources are creating circular waves in a pool. You have a little remote controlled motor boat and gently move it to a location where it does not move up or down. The boat is 13.7 m from one source and 15.2 m from the other source. Very slowly, you now move the boat across a section where it experiences lots of wave action, and settle it into the next quiet spot. At this time, the boat is 12.1 m from one source and 13.0 m from the other source. Determine the wavelength of the water waves.
