Question: Hint 3 . Find the condition for perfectly destructive interference In general, if d a and d b are the paths traveled by two waves

Hint 3. Find the condition for perfectly destructive interference
In general, if da and db are the paths traveled by two waves of equal frequency that are originally emitted in phase, the condition for perfectly destructive interference is
da-db=n2
where is the wavelength of the sound waved and n is any nonzero odd integer.
Given this condition for perfectly destructive interference and the situation described in the introduction of this problem, then, what is the value of n that corresponds to the shortest distance db?
