Two beams of coherent light start out at the same point in phase and travel different paths to arrive at point P. If the maximum constructive interference is to occur at point P, the two beams must travel paths that differ by a whole number of half-wavelengths. an odd number of half-wavelengths. O a whole number of wavelengths.
