6. Moe, Larry, and Curly stand in a line with a
spacing of 1.00 m. Larry is 3.00 m in front of a
pair of stereo speakers 0.800 m apart, as
shown in Figure 28-43 . The speakers produce
a single-frequency tone, vibrating in phase
with each other. What are the two lowest
frequencies that allow Larry to hear a loud
tone while Moe and Curly hear very little?
