A glass sheet measuring 10cm X 25cm is covered by a very thin opaque coating. In the middle of this sheet is a thin, straight scratch 0.00125mm thick. The sheet is totally immersed beneath the surface of a liquid having an index of refraction of 1.45. Monochromatic light strikes the sheet perpendicular to its surface and passes through the scratch. A screen is placed under water a distance 30cm away from the sheet and parallel to it. You observe that the first dark fringes on either side of the central bright fringe on this screen are 22.4c, apart. What is the wavelength of the light in air?
