The diagram shows an experiment which has been set up to demonstrate two-source interference, using microwaves of wavelength λ. The detector is moved from O in the direction of the arrow. The signal detected decreases until the detector reaches the point X, and then starts to increase again as the detector moves beyond X. Which equation correctly determines the position of X?
