[answerhappygod]

An electric current through mercury gas produces several
distinct wavelengths of visible light. What are the wavelengths (in
nm) of the mercury spectrum, if they form first-order maxima at
angles of 31.16°, 34.53°, 45.22°, and 53.08° when projected on a
diffraction grating having 13,000 lines per centimeter? (Round your
