Two identical loudspeakers are situated at the same height above a horizontal xy-plane and emit sound waves of frequency 1660 Hz. The speakers are located at coordinates (0,1.57) and (0,-1.57), with units in meters. A point O on the x-axis a distance x1 = 9.1 meters away (x1,0) is the location of an interference maximum. A second point P at (x1, y2) is the location of the first minimum of sound intensity when moving away from point O in the y-direction. Points O and P are at the same height as the two speakers. What is the value of y2 (in meters) for point P?

Two stereo speakers mounted 4.52 m apart on a wall emit identical sound waves. You are standing at the opposite wall of the room at a point directly between the two speakers. You walk 2.11 m parallel to the wall to a location where you first notice that the sound intensity is much less. If the wall along which you are walking is 13.3 m from the wall with the speakers, what is the wavelength of the sound waves? (Answer:...
