The average depth of penetration of an ultra-sound wave of the frequency f = 800 kHz in tissue is 4 cm. The initial intensity of this wave was 10 W/m2. What will the intensity of this wave be at the depth x = 120 mm?
Two identical loudspeakers 2.0 m apart are emitting 1800 Hz sound waves into a room where the speed of sound is 340 m/s. Is the point 4.0 m directlyin front of one of the speakers, perpendicular to the line joining the speakers, a point of maximum constructive interference, perfect destructive interference, or something in between?
Two loudspeakers placed 6 m apart are driven in phase by an audio oscillator whose frequency range is 950 Hz to 1350 Hz. A point P is located 5 m from one loudspeaker and 3.5 m from the other. The speed of sound is 350 m/s. The frequency produced by the oscillator, for which constructive interference of sound occurs at point P, is closest to what?
