A source emits two narrow spectral lines at wavelengths of 600.00nm and 600.02nm. a) Can a diffraction grating with 500 lines/mm and a width of 1.6cm be used to resolve the two wavelengths at normal incidence (0; = 0)? Why? b) If an air-spaced (n =1) Fabry-Perot interferometer with a mirror spacing of Imm is to be used to resolve the two wavelengths, what is the minimum necessary mirror reflectivity? [Assume R1 = R2 and 0, 0.] A source emits two narrow spectral lines at wavelengths of 600.00nm and 600.02nm. a) Can a diffraction grating with 500 lines/mm and a width of 1.6cm be used to resolve the two wavelengths at normal incidence (0; = 0)?
