    Sound exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. A person is sitting at an angle off to the side of a diffraction horn that has a width D of 0.060 m. The speed of sound is 343 m/s. This individual does not hear a sound wave that has a frequency of 8100 Hz. When she is sitting at an angle (angle/2), there is a different frequency that she does not hear. How do you find the frequency?
