2.Two compact sources of sound near each other produce in-phase sine waves ateach source. One source is positioned at a distance x, =12.00 m from a microphoneand the other source is positioned at a distance of x, =13.40 m from the samemicrophone. The amplitude of the sound at the microphone from each source by itselfis s, = 0.0350µum. The plane waves come from essentially the same direction so therewill be interference.a. If the frequency emitted by the two sources is f = 425.0Hz and the speed ofsound is v= 340.0m / s, what is the phase difference, 8 , in radians, due to thepath length differences to the microphone?b. When both sources are on, interference changes the total amplitude tos, = 2s, cos(S / 2). What is the total amplitude for the phase difference found inpart 'a.'?

Solution: a) The phase difference is calculated as: We know that, Wavelengthλ=vf Given that,…

Answered: 2. each source. One source is…

Two loudspeakers in a plane are 2.0 m apart and in phase with each other. Both emit 700 Hz sound waves into a room where the speed of sound is 341 m/s. A listener stands 5.0 m in front of the loudspeakers and 2.0 m to one side of the center. a)ls the interference at this point maximum constructive, maximum destructive, or in between? b)How will the situation differ if the loudspeakers are out of phase? Step 1: SKETCH the situation. Step 2: Draw the distance r₁ from source 1 to the point and the distance r₂ from source 2 to the point Step 3: Find 1 and 2, then calculate Ar. Step 4: Find the wavelength Step 5:Find the phase difference at that point.
9. Two speakers are facing each other and producing a single pure tone. You are standing between the two speakers. The loudness goes from a maximum, down to a minimum and back to a maximum as you move a distance of d = 3.5 m towards one of the speakers. What is the wavelength of the sound wave produced by the speakers?

4. Two side-by-side (virtually no separation) speakers are wired such that they emit a single-frequency sound out of phase with each other by radians, and radially-outward. The tone heard from the two speakers combined has a decibel level of 36 dB. a. If one of the speakers is suddenly disconnected, what is the decibel level heard? b. If both speakers are connected and the listener moves to a distance from the speakers that is 5 times greater than where the 36dB sound was heard, what is the new decibel level heard? Assume that the waves travel radially from the speakers.

Ultrasonic diagnostics may be used to locate a tumor in an organ such as the liver. The figure shows a beam of ultrasonic waves that enter the surrounding medium, refract into the liver, reflect off the tumor, and refract back into the surrounding medium. If the speed of the wave as it travels through the liver is 5.7% less than when it is traveling through the surrounding medium, determine the depth of the tumor. cm Surrounding material 14.0 cm 55% Liver Tumor
