Nettet16. sep. 2016 · Spectral lines are broadened for a number of reasons (both internal to the system--perhaps states are mixing, and external--the pressure on the system has some effect on line widths). However one type of broadening that is inherent to all systems (including simple, little hydrogen) is something called "lifetime broadening," and it is a … Nettet29. jun. 2024 · The black lines, over 600 of them, are due to the absorption of particular wavelengths of light by chemical elements in the outer layers of the Sun. This means that if we measure the wavelength of these black lines, we can identify what elements there actually are in the Sun. Emission and Absorption Spectrum: JEE Chemistry Concepts …
