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?

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
