Number of interference fringes based on n open slits

[sqljunkey]

Hi,

Is there an equation that gives you the number of interference fringes if you know the light wave length, size and separation of the slits, and length from the slits to the screen?

Absolutely. Have you searched Google for “ interference for n sources” ? It really is just standard book work. Same formulae for multiple RF antennae if you find any problems.
