Incident intensity vs transmitted intensity

WebJan 4, 2024 · For each wavelength, researchers also remove the glass sample and send the beam directly to the detector, giving them a way to assess the light’s intensity before and … WebFeb 12, 2024 · 2.1.5: Spectrophotometry. Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength.
