c. The Lyman-a hydrogen solar emission line at 121.58 nm corresponds to an elec- tron dropping from a higher energy level down to n = 1. Use the Rydberg equa- tion to identify the transition. to = 1 5. Colorful lights used in advertising are commonly referred to as "neon lights." If these lights act like large gas discharge tubes, do all "neon lights" contain neon? Explain. 6. A fireworks display is based on the same principles as flame tests,...

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...
