Sound Wave Interference

  1. Apr 20, 2009 #1
    1. The problem statement, all variables and given/known data
    Two speakers, one directly behind the other and along the x-axis, emit sound waves along the x-axis. The speaker in the back emits sound with a wavelength of .02 m and the speaker in the front emits waves with a wavelength of .05m. If the two speakers are separated by 3 m, where along the x-axis will destructive interference first occur?


    2. Relevant equations
    d sin(theta) = m(wavelength)


    3. The attempt at a solution
    How do I use the above equation if there are two wavelengths that I need to use?

    Am I using the correct equation?
