Reference no: EM13666971

Light of wavelength 579 nm shines down on two glass plates, spaced at one end with a thin piece of paper. Looking down on the plates (the figure shows a side view only), 26 bright interference fringes are observed across the top plate by a dark fringe at the end by the paper.
