How to measure background radiation
WebWe present an analysis of galaxy and QSO absorption line pairs toward 24 QSOs at redshifts between and 1 in an effort to establish the relationship between galaxies and absorption lines in physical proximity to QSOs. … Webabsorption measurements can give both qualitative and quantitative info about sample. Photoluminescence spectroscopy emission of photons is measured following absorption. most important types = fluorescence and phosphorescence spectroscopy. Attenuate = to decrease the energy per unit area of a beam of radiation.
