Interference for a lattice with N slits
OK, so check out the first formula (the one for intensity) in the following pdf:
http://folk.ntnu.no/magnud/OvLf/bolge/oving11.pdf
It's the formula for Intensity as a function of angle from the interference for a lattice with N very thin slits.
Mathematically, why is ##I_{max}## found only when BOTH the numerator and denominator are approaching zero?
I agree that the intensity is largest when the ratio between the numerator and denominator is biggest, but why does this only happen when both approach zero?
