Upload answer sheets Two glass plates are held together at one end to form a wedge of air that acts as a thin film. A broad beam of light of wavelength 480 nm is directed through the plates, perpendicular to the first plate. An observer intercepting light reflected from the plates sees on the plates an interference pattern that is due to the wedge of air. How much thicker is the wedge at the 16th bright fringe than it is at the 6th bright fringe, counting from where the plates touch? (10 Marks) Sync to check your submission
