Transcription: In this activity you're going to explore the quantum world of the atom, a world that was discovered in the first few decades of this century and which scientists have continued to explore and exploit ever since. This is a world of energy levels, of emission and absorption spectra, and of electron clouds associated with quantum states. All of these aspects of quantum physics are intimately related and you're going to explore these relationships. You'll manipulate atoms, causing them to make transitions from one quantum state to another. And you'll investigate the emission and absorption lines i ...
