Решение задачи по физике раздел 41 пункт 68 волны

68. Two speakers spaced d = 0,5 m apart and reproduce the same musical tone at a frequency ν = 1500 Hz. The receiver is located at a distance l = 4 m from the center speaker. Taking the sound velocity υ = 340 m / s, determine at what distance from the center line parallel to the dynamics necessary to push the receiver, so he gave the first interference minimum.
