Stories about: energy state

New Quantum Theory Test Uses Electrons Rydberg's constant, is a physical measure specifying the exact light frequency given off by an atom while an electron jumps from a certain energy level to a lower one. This number is critical for light spectroscopy techniques trying to determine the concentrations and types of chemical elements inside distant st... 30 April 2008 09:25 GMT How Light Sticks Work What's better than having a light source that uses neither batteries nor light bulbs, gives off an intense light emission, lights up no matter if it's held underwater or in plain air and can be carried wherever you may go?
