Sound Waves length measurement

  1. Oct 29, 2013 #1
    1. The problem statement, all variables and given/known data

    Two sources, A and B, emit a sound of a certain wavelength. The sound emitted from both sources is detected at a point away from the sources. The sound from souce A is a distance d from the observation point, whereas the sound from source B has to travel a distance of 3.7λ. Take v to be 340 m/s.

    a) What is the largest value of the wavelength, in terms of d, for the maximum sound intensity to be detected at the observation point?

    b) If d = 14.1 m and the speed of sound is 340 m/s, what is the frequency of the emitted sound?

    2. Relevant equations



    3. The attempt at a solution

    How you have attempted at the solution?

    I have attempted at the solution by using the equation |d1-d2|= n*(Wavelength) n=0,1,2... ,which is the equation constructive interference of waves.
    However, i am not sure that i'll gonna use this formula for the maximum sound intensity
