Two 2.5 W speakers are 5.0 m apart and emit identical sound waves. When you are at point P, 12.0 m in front of the plane of the speakers and centered between them, you hear a sound of maximum intensity. a) what is the sound level that you hear at point p? B) as you walk parallel to the plane of the speakers, you hear the first minimum of sound intensity when you are directly in front of one of the speakers at point Q. What is the wavelength of these sound waves?
