2) Light from glowing hydrogen contains many discrete spectral lines, of which two are Ha (hydrogen-alpha) and HE (hydrogen-beta), with wavelengths of 656.3 nm and 486.1 nm, respectively. Find the first-order angular separation between these wavelengths in a spectrometer that uses a grating with 6000 slits per cm. (
