In the figure, two isotropic point sources of light (S1 and S2) are separated by distance 2.40 µm along a y axis and emit in phase at wavelength 930 nm and at the same amplitude. A light detector is located at point P at coordinate xp on the x axis. What is the greatest value of xp at which the detected light is minimum due to destructive interference? S1 P S2 Units Number
