Atomic Line Spectra

Atomic line spectra are specific colors of light emitted or absorbed by atoms. When atoms are energized, their electrons jump to higher energy levels; as they return to lower levels, they release light at particular wavelengths, creating distinct lines in a spectrum. These lines serve as unique fingerprints for each element, allowing scientists to identify the presence of specific atoms in stars, galaxies, or laboratory samples. Essentially, atomic line spectra are the characteristic "colors" that reveal the atomic structure and composition of matter through light analysis.
