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