Different size slits in Young's double slit experiment

[Dima Petrukhin]

Hi all
I was wondering what happens if one slit in youngs double slit is bigger than the other?
I recon that the of maxima will rise and in minima, there will be no dark spot, but dim light instead. Is that correct? If not can you please explain what happens?
Thanks

Could this be a homework question, by any chance? It sounds like one. (See the thread near the top of the forum thread list)
A simple, approximate approach would be to treat the wider slit as two slits with one slit the same width as the narrow slit, which would produce a 'perfect' set of fringes and then the remaining part of the wide slit will fill in the nulls and slightly alter the shapes of the peaks. Rough and ready but a useful start.
