The Colors of All Glowing Objects Have the Same Origin

question 87

Multiple Choice

The colors of all glowing objects have the same origin: They come from atoms and molecules that have been excited to states of high energy. Atoms in burning fireworks and stars become excited by absorbing energy as heat. They then throw off their excess energy as light. The colors emitted by an atom depend on how its electrons are arranged. So by investigating the colors an atom emits, we can determine its internal structure.
