UTF-8Excitation and deexcitation: Day 1, P1Let there be light!
Photons come in different colors!
In the model below we've introduced two new kinds of atoms, purple ones and green ones, plus a blue atom that you can steer with the arrow keys. The atoms have different energy levels, too. Hit "Run" and use the blue atom to excite the green and purple ones. Observe the different photons that they emit.
