Electrons and how they interact with electromagnetic fields are important in our understanding of chemistry and physics. In the classical view, the energy of an electron orbiting an atomic nucleus is larger for orbits further from the nucleus of an atom. However, quantum mechanical effects force electrons to take on discrete positions in orbitals. Th… WebbActive laser medium or gain medium: Laser medium is the heart of the laser system and is responsible for producing gain and subsequent generation of laser. It can be a crystal, …
