question

AFabry-Perot etalon is adjusted so that for a wavelength of 5461A°, interference fringes are observed in a tele-scope focused for infinity. The etalon, of thickness 1.01 cm, is enclosed in a box with transparent windows from which the air can be exhausted. It is found that there is a shift of one fringe when the pressure is changed by 6.46 cm Hg. Find the index of refraction of the air at room temperature and at the original pressure, which was 77 cm Hg.
