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 ) ( 300 m, 800m) a point of maximum constructive interference, perfect destructive interference, or something in between?
Please Help! THank you

It is not possible to answer this question without knowing the precise phase relationship between the signals as applied to the aerials. "Out of phase" simply means that the signals are not exactly in-phase, but this is not sufficiently precise for an answer to be found. It is possible that your teacher means to say that the signals are in antiphase (i.e. the phase difference is 180deg). But if so he or she must state that explicitly. So you must ask your teacher what the precise phase angle is intended to be.

you're lacking a great number of the question. The ? - axis ?? what's this axis and the way does it relate to the antennae. 3.0 whats? How far aside are the antennae? and the place is the factor which you're asking approximately?
