Two identical microwave antennas act as coherent sources and emit waves of wavelength 0.050m. A detector is placed at a point where the phase difference between the arriving waves is 240∘.
(i) Convert the given phase difference to radians.
(ii) Determine the corresponding path difference between the waves at the detector.
(iii) Will the detector register a maximum or a minimum in intensity at this point? Justify your answer with suitable reasoning.
