Problem: Two out-of-phase radio antennas at X =  ± 300m on the x-axis are emitting 3.0 MHz radio waves. Is the point (x,y) = (300m, 800m) a point of maximum constructive interference, perfect destructive interference, or something in between?

Relationship between speed, frequency and wavelength:

v=fλ

Condition for constructive interference:

x=mλ

Condition for destructive interference:

x=(m+12)λ

Where Δx is the path difference and m is an integer.

m = 1,2,3...

The above conditions apply when the sources are coherent (in-phase). 

When the sources are out of phase, the conditions are reversed. That is Δx = mλ describes condition destructive interference.
