Homework Statement
The question is as follows, I'm truly stuck where to start here, any help would be much appreciated:
A transparent paper of refractive index 1.45 and thickness 0.02mm is pasted on one of the slits of a double slit experiment. Monochromatic light of wavelength 620nm is passed through the slits. How many fringes will cross through the centre if the paper is removed?
Homework Equations
I have been provided with one equation for this, which is as follows:
Yo=β/λ(n-1)t
Where n is the refractive index and t is the thickness.
The Attempt at a Solution
Truly stuck where to even begin I'm sorry to say.
