Q. Sound waves of frequency 569 Hz enter a window 1.25 m wide. The window is in the exact center of one wall of a theater 24 m by 12 m. The window is 12 m from the opposite wall, along which is a row of seats occupied by people. The theater is acoustically prepared to prevent the reflection of sound waves, and the speed of sound is 330 m/s. Two people, on each side of a line directly in front of the window, in the row along the wall hear no sound. What minimumdistance are they from each other? The angle may be too large to use small angle approximation. Answer in units of m.
