*The graphs above were generated using a MATLAB algorithm developed for this project and represent the mathematical data of the Bohr Atomic Model (Balmer Series).
The colored lines and sharp peaks visible in the top panel of the graph represent the "Emission Spectrum".
Just like in the 3D animation you witnessed; when an excited electron falls to a lower energy level, it releases the energy difference as a photon (light). Glowing nebulas in deep space or neon signs on the street operate on this principle. It is the atom's unique colors glowing against the darkness.
The black bands and deep dips across the rainbow in the bottom panel of the graph represent the "Absorption Spectrum".
If light from a star passes through a cloud of cold hydrogen gas, the hydrogen atoms "swallow" only the specific frequencies they love (656nm, 486nm, etc.). When the remaining light reaches us, those swallowed parts are missing. These dark lines are essentially barcodes that allow us to read the identity of stars.
Each peak or dip in the MATLAB graph corresponds to these precise transitions in the atomic world. These four lines are the unchanging signature of the Hydrogen atom, no matter where in the universe they are found.
