What is the magnitude of the phase difference at detector

Reference no: EM13309803

Sources A and B emit long-range radio waves of wavelength 340 m, with the phase of the emission from A ahead of that from source B by 90 °. The distance rAfrom A to a detector is greater than the corresponding distance rB from B by 120 m. What is the magnitude of the phase difference at the detector?
