Discuss the below:
Q: Moe, Larry, and Curly sit in a line with a spacing of 1.00 m. Larry is d1 = 3.0 m in front of a pair of stereo speakers d2 = 0.800 m apart, as shown. 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? (Take the speed of sound to be 343 m/s.)
(a) lowest frequency
(b) second lowest frequency
