Two radio antennae are producing radio (electromagnetic) waves, in phase, at a wavelength of 250m.

A) What is the frequency of the wavelength?

B) The two antennae and the point P are at the three corner of a right triangle as shown, and the point P is a distance r1 = 2250m from antenna 1. If the point P is at the m = 3 maximum of the interference pattern, what is the distance, d, separating the two antennae? . (Note: distance between the sources and the point P is NOT much greater than the separation d).
