Physicists realize an atom laser, a source of coherent matter waves
... waves start to oscillate in concert - a coherent matter wave forms that comprises all particles in the ground state of the system. This transition from “disordered” to coherent matter waves can be compared to the step from incoherent light to laser light. Indeed, atom lasers based on BoseEinstein co ...

What will happen to extra energy when the electron moves to the lowest state? n The left over energy when the electrically charged electron moves from a high state to a lower state is emitted in the form of a single packet ...
