WARNING NOOB QUESTION FOLLOWS: Well this has been bugging me lately, as i have been doing research on maxwells equations. In chemistry i was taught that light from chemical reactions comes from electrons jumping from a higher orbit to a lower one. But is ALL light emitted this way, or only light that comes from chemical reactions? For instance, are the electrons in my desk always jumping to create the brown color of wood? In my research i found that a changing electric field creates a magnetic field that also is changing to create an electric field. And this creates light. I do not doubt that the electrons jumping down an orbit gives off light, but is the only thing that gives off light? This would mean all object's electrons jump from the exact same point to give off the exact same color at all times.
