Q1. Sound waves of frequency 502 Hz enter a window 1.18 m wide. The window is in the exact center of one wall of a theatre 24 m by 14 m. The window is 14 m from the opposite wall, along which is a row of seats occupied by people. The theatre is acoustically ready to stop the reflection of sound waves, and the speed of sound is 330 m/s. Two people, on each side of a line straight in front of the window, in the row along the wall hear no sound.

What least distance are they from each other? The angle might be too large to use small angle approximation.

Answer in units of m
