Fluorescence/Phosphorescence Due in 8 hours, 33 minutes You are shining ultraviolet light on a gas of an unknown element. You know that an electron starts in a ground state with an energy of -12.10 eV. The electron absorbs a 4.00-eV photon. The electron immediately drops to an intermediate energy state $E_{inter}$ of energy -10.50 eV (in this case we will assume it emits a photon when it drops to the intermediate state, though most often the energy is lost through other means). The electron promptly drops back down to the ground state. What is the energy of the state which the electron is in after absorbing the UV photon? What is the energy of the first photon emitted? What is the energy of the second photon emitted and is this process considered fluorescence or phosphorescence? (Both answers must be correct for the answer to be correct.) O fluorescence O phosphorescence

COMMONLIT Name: Class: For Teens, A Good Mood Depends on Good Sleep Sleeping less than eight hours - or more than 10 - makes teenagers feel worse the next day By Meenaskshi Prabhune 2017 How many hours of sleep do you get a night? Likely not as much as Andrew Fuligni finds teenagers should get in his new study. In this informational text, Meenaskshi Prabhune discusses how many hours of sleep teenagers should get each night to be at their best the next day. As you read, take notes on why teenagers may not be getting enough sleep. [1] For families with teenagers, school nights may fall into a familiar pattern. Parents urge their kids to go to bed early. But teens would rather stay up late. Maybe they have homework or want to spend time with friends. Or maybe it's just hard to fall asleep. But a new study confirms that adolescents $ { }^{1} $ need eight to 10 hours of sleep at night to feel their best the next day. As kids reach adolescence, they often face increasing workloads and responsibilities. But they are not yet adults. Their bodies and brains are still changing. As a result, "Their sleep needs are like that of a developing "Untitled" by minh ?ô is licensed under CCO. child," says Rafael Pelayo. He is a sleep doctor at the Stanford Center for Sleep Sciences and Medicine in California. He was not involved in the new study. "Adolescence is sometimes referred to as the 'perfect storm' of problems of sleep," says Pelayo. On the one hand, teens need regular sleep to be mentally and physically healthy. But their internal clocks $ { }^{2} $ shift during this period. Their bodies want to stay awake later at night and sleep later in the morning. School still starts early, though. As a result, Pelayo estimates that 80 to 90 percent of teens do not get enough sleep. That missed sleep has consequences. $ { }^{3} $ Sleep-deprived kids are more prone $ { }^{4} $ to mental and physical illnesses. Sleepy drivers face a heightened risk of car accidents - the top cause of teenage death. But too much sleep can have its own problems, such as leaving teens with a sour mood upon waking. 1. Adolescent (noun) a young person in the process of developing from a child into an adult 2. a system in the body that controls when a person sleeps, eats, and performs other necessary functions 3.
