Two stereo speakers are separated by a distance of 2.40m. A person stands at a distance of 3.20 m directly in front of one of the speakers as shown in figure. Find the frequencies in the audible range (20-2000 Hz) for which the listener will hear a minimum sound intensity. Speed of sound in air = 320 m s⁻¹. Choose the option containing the correct final result.
