Interference Pattern Effects
The fringe separation (Δy) is given by: Δy = λD/d
Where λ is wavelength, D is screen distance, and d is slit separation.
For clear fringes, the condition s/S < λ/d must be satisfied (s = source width, S = source distance).
Current condition: s/S = 0.00125, λ/d = 0.0029 → Fringes visible
