A Michelson interferometer splits a beam of light of unknown wavelength producing a bright fringe (i.e., all of the intensity) at the detector. As one mirror is moved a distance 2.1 microns from its original position, exactly 7 new fringes are observed to appear at the detector. What is the wavelength of the unknown light?
