Two radio frequency point sources separated by 1.8 m are radiating in phase at a wavelength of 0.60 m. A detector moves in a circular path around the two sources (in the plane containing the two sources).
a) How many maxima does the detector detect?
b) Suppose the detector moved around the two sources in an elliptical path, how many maxima would the detector detect?
