Spinach absorption spectrum
WebThe absorption of a photon by an atom or molecule can be represented using energy level diagrams. Consider the absorption of a photon by a hydrogen atom at 434.0 nm. This corresponds to the absorption of a photon that possesses the energy difference between n = 3 and n = 2. When a visible wavelength photon is absorbed by an atom or WebSep 15, 2024 · The absorption spectrum measured with our TO spectrometer is shown in the following graph.
