Moe, Larry, and Curly stand in a line with a spacing of 1.00m. Larry is 3.00m in front of a pair of stereo speakers .800m apart. The speakers produce a single-frequecy tone, vibrating in phase with each other. What are the two lowest frquencies that allow Larr to hear a loud tone while Moe and Curly hear very little?
