I was wondering if anyone knew what the intensity of subsidary maxima was?
My intuition would tell me that it would be the square of the amplitude of the wave illuminating the slits (I am thinking of the phasor diagram and what the net phasor may be as the angle is increased from one minimum to another.) On the other hand my lecturer said that the subsidary maxima arise as you increase the number of slits, so that would suggest that the intensity is dependent on N? I'm not sure if he may just have been talking about their intensity relative to the principal maxima, whose intensity I know increases as the square of the number of slits. So then indeed subsidary maxima would appear to vanish as N is increased simply because their intensity is not changing but the principal maxima intensity is increasing as a square.
Unfortunately I have not been able to find anything discussing the intensity of the subsidary maxima...
