9. (6 pts. Two spectral lines in a mixture of hydrogen and deuterium gas have wavelengths of 656.30 nm and 656.48 nm, respectively. a. Determine the number of lines a transmission diffraction grating must have to resolve these two wavelengths in first-order. b. What is the resolving power of the grating in first-order? c. What is the spacing between adjacent slits if the grating is 5 mm wide and is fully illuminated?
