Hi Young,

What have you done with this problem so far? Have you tried to calculate the effective difference in the path length? If you share your thoughts/ideas in this problem, it will be easier for us to help.

Also, what's "dinanzi"? Is it an Italian word?

Ehm, yes,some trouble with google translator :)
"dinanzi"= in front

If you want, edit my first message. Thanks

My problem is that I do not succeed to take advantage of the various measures of two slits.Usuallly I have only worked with one interference slit.

I creed that in reality is from only using one formula like this:

$$2nd=(m + 1/2) \lambda$$

where
lambda is the distance, n=1.50, d= thickness of slit ad m=0,1,2..
