Consider the double-slit arrangement shown in the figure below, where the separation d is 0.305 mm and the distance L is 1.10 m.
A sheet of transparent plastic (n = 1.50) 0.0491 mm thick (about the thickness of a piece of paper) is placed over the upper slit. As a result, the central maximum of the interference pattern moves upward a distance y'. What is y'?
I know that Y=Ltan(angle) i have tried to manipulate the numbers and attempted to find theta but it just doesn't want to work...please any help is much appriciated.
