Variable costing does not determine a per-unit cost of fixed overheads, while absorption costing does. Variable costing will yield one lump-sum expense line item for fixed overhead costs when ...

Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

NASA’s Hubble Space Telescope marks its 100,000th exposure, capturing a dazzling quasar 9 billion light-years away with a ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...
