Two optically flat glass plates, 16.0 cm long, are in contact at one end and separated by 0.0200 mm at the other end.
The space between the plates is occupied by oil with index of refraction 1.45. The index of refraction of the glass plates is 1.55. The plates are illuminated at normal incidence with monochromatic light, and fringes are observed. If the dark fringes are spaced 2.00 mm apart, what is the wavelength of the monochromatic light?
A) 525 nm B) 475 nm C) 675 nm D) 425 nm E) 725 nm
