K 2. Point Source Interference Pattern Consider a two-dimensional x-y space in which there are two identical and synchronized point sources located at y=±D/2 emitting waves of wavelength λ. The sources are said to constructively interfere at any location if the phase difference between waves received from the two sources at that location differ by an integral multiple of 2π. Equivalently, the distances from the location to the two sources differ by an integral number of wavelengths. Derive the complete...
