Find by how much does the film thickness change

Reference no: EM13649173

A broad beam of light of wavelength 692 nm is incident at90° on a thin, wedge-shaped film with index of refraction 1.50.An observer intercepting the light transmitted by the film sees 16bright and 15 dark fringes along the length of the film. By how much does the film thickness change over this length?
