Passing an electric current through an unknown gas produces several distinct wavelengths of visible light. In this problem, you will find the wavelengths of the unknown spectrum by observing that they form first-order maxima at angles of 24.2°, 30.5°, 35.3°, and 41.7° when projected on a diffraction grating having 10,000 lines per centimeter.
(a) What is the wavelength (in nm) for the line at 23.80°?
(b) What is the wavelength (in nm) for the line at 30.20°?
