Question about sound

  1. Jul 9, 2008 #1
    1. The problem statement, all variables and given/known data

    One microphone is located at the origin, and a second microphone is located on the +y axis. The microphones are separated by a distance of D=1.5 m. A source of sound is located on the +x axis, its distances from microphones 1 and 2 being L1 and L2, respectively. The speed of sound is 343 m/s. The sound reaches microphone 1 first, and then .00146 s later, microphone 2. Find the distances L1 and L2


    2. Relevant equations



    3. The attempt at a solution

    L1= x
    L2= x + (343 * .00146)

    1.5^2 + X^2 = (x+ (343*.00146))^2
    x= 1.996

    L1=1.996
    L2=2.4968

    Units!

    L1 = 1.996 lightyears? meters? yards? GeV-1?
