What is the thickness of the mica

Reference no: EM13560840

A thin flake of mica (n = 1.58) is used to cover one slit ofa double-slit interference arrangement. The central point on theviewing screen is now occupied by what had been the seventh brightside fringe (m = 7) before the mica was used. If = 525 nm, what is the thickness of the mica? (Hint:Consider the wavelength within the mica.)
