In the figure below, sources A and B emit long-range radio waves of wavelength A = 450 m, with the phase of the emission from A ahead of that from source B by 90°. The distance rA from A to detector D is greater than the corresponding distance rg by 60 m. What is the phase difference at D? 0.17 x xA
