A planar cross section through two spherical waves emanating from the sources S1 and S2 in the plane is shown in the figure. S1 and S2 are in phase. The black circles are one and two wavelengths from their respective sources. The lighter circles are one-half and one-and-a-half wavelengths distant from their respective sources. If the waves shown arriving at P1 both arrive with amplitude A, the resultant amplitude at point P1 is
