An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles of 24.2o,25.7o,29.1o,and 41.0o .when projected on a diffraction grating having 10,000 lines per centimeter? (a) What do the four angles in the above problem become if a 5000-line-per-centimeter diffraction grating is used? (b) Using this grating, what would the angles be for the second-order maxima? (c) Discuss therelationship between integral reductions in lines per centimeter and the new angles of various order maxima.
