Re: [Phys-l] Online Textbooks



Our old AO Spencer Spectrometers (the manual is copywritted 1938) are
starting to show war and tear. We are looking to buy new spectrometers.
Could anyone please make some recommendations? What do folks use these
days to measure the position of, say, Hydrogen lines?
