r-shaped room Has wall and back wall wiati m, and long. Along the front wall are two loudspeakers, 3.70 apart, With the nter point them coinciding with the center point of the wallI. The speakers emit (in phase with each other) a sound wave with a single frequency. A maximum of sound intensity is heard at the center of the back wall, 5.20 m from the center of the front wall. What is the highest possible frequency (in Hz) of the sound from the speakers if no other maxima are heard anywhere along the back wall? Assume the speed of sound is 343 m/s. Hz
