Interference Patterns for Light - 3 Factors

http://www.stmary.ws/highschool/physics/home/notes/waves/LightWave.htm
The laser light in this demonstration passes through a piece of clear plastic containing very tiny slits that are closely spaced.
When the light wave passes through these slits it produces an interference pattern that consists of alternating bands of bright and dark lines. Bright lines come from constructive overlap, darks lines - destructive. The spacing between the bright lines are determined by 3 factors - distance between the slits, wavelength of light used and the distance between the slits and the screen.

very very helpful. I was wondering if interference patterns could change at all according to number of slits or different wave sources or something - this has clarified the issue :D
