Unformatted text preview: corresponding orders of the fringes. (c) Calculate the free spectral range and spectral resolution of the Fabry-Perot interferometer. 2. Calculate the minimum spacing between the plates of a Fabry-Perot interferometer which would resolve two light waves with wavelength difference 0.01 nm at 500 nm. Assume the reflectivity R to be 0.9....
