Got it! Thanks a WHOLE lot!

There's another follow on question..
Show that interference maxima is given by


Ignoring part c) for the time being, how exactly is pr density related to the interference maxima equation?

how the prob density equation just found is related to the interference equation.

There's no need to relate the probability density to the interference pattern, the question simply asks you to derive the fringe separation, which can be done without using the probability density.

hmm? It says "Using the results obtained in (a) [The pr density part], show that the interference maxima are given by..."

Okay, how does the maxima relate to [itex]\rho[/itex]? What is a maxima?

So derive [itex]\rho[/itex] in terms of [itex]\psi[/itex] and set to zero?
What about A (imaginary number?)

Also, where would lambda come from?

Who would one set [itex]\rho[/itex] to zero? Wouldn't a maxima occur when [itex]\rho[/itex] is greatest?

The maximum value of [itex]\rho[/itex] is 1, or at least that is what I think. But where to from there?

Correct, therefore the maximum value of [itex]\rho[/itex] is...?
