atomic transitions

**atomic transitions**

Atomic transitions refer to the changes in energy levels of electrons within an atom. When an electron moves from one energy level to another-either absorbing or emitting energy-this shift is called an atomic transition. These transitions are fundamental to understanding phenomena such as atomic spectra, quantum mechanics, and the behavior of light and matter at the microscopic scale. Atomic transitions play a critical role in fields like spectroscopy, astrophysics, and laser technology.
