Wave Optics: Interference in thin films/wedge shaped film.
Not what you're looking for?
Two rectangular optically flat plates (n=1.52) are in contact along one end and are separated along the other end by a 2.00 micrometer thick spacer. The top plate is illuminated by monochromatic light of wavelength 546.1 nm. Calculate the number of dark parallel bands crossing the top plate (including the dark band at zero thickness along the edge of contact between the two plates).
