Two coherent sources emit waves that have a wavelength of 0.44 m.

Two coherent sources emit waves that have a wavelength of 0.44 m.
Determine whether constructive or destructive interference occurs at a point
whose distances from the two sources are as follows: 1.32 and 3.08m

I'll rate if someone please explain this :)

If the distance is 92n+1) times the wavelength, where n is any integer, the interference is destructive. hence the iterference is destructive in both cases as 1.32/0.44=3, 3.08/0.44=7.
