WebStudents will see spectra going both right and left, and may see more than one spectrum in each direction. Depending on the grating type, either the left or right spectrum may be … Spectral lines are the result of interaction between a quantum system (usually atoms, but sometimes molecules or atomic nuclei) and a single photon. When a photon has about the right amount of energy (which is connected to its frequency) to allow a change in the energy state of the system (in the case of an atom this is usually an electron changing orbitals), the photon is absorbed. The…
