In Young s double slit experiment a thin transparent sheet

Last updated: 6/10/2023

In Young s double slit experiment a thin transparent sheet of thickness t and refractive index is introduced in the path of one of the interfering beams This shifts the entire fringe system through a constant distance Now estimate the thickness of the sheet if the fringe system displacement is S Assume that the distance between slits is 2d distance between slits and screen is D Ans t D 1 2Sd
