Question

Consider the usual two-point-source interference pattern (with point sources a distance d apart emitting synchronously with wavelength ë) except that in this case, one of the two sources sends out a wave whose amplitude is A and the other’s amplitude is (5/2)A. Calculate the intensity far from the sources as a function of angle from the perpendicular bisector of the two sources. a. b. c. d. BS 3. What is the intensity as a function of phase lag f? In which directions (specified by q, the angle away from the perpendicular bisector of the two sources) is the intensity a maximum? In which directions is the intensity a minimum? What are the minimum and maximum intensities?
