Suppose that the n=10 state of He+ decays to the n=4 state in about 0.0079s. The n=4 state decays to the ground state in about 6.0e-9 s. Suppose you build a laser in which the gain medium consists of singly ionized helium, using the previously described quantum states, what is the wavelength of light produced by this laser?

Astronomers use the line emission from the quantum state n = 3 to n = 2 to probe ionized hydrogen gas – that is, hydrogen gas stripped of its electron. In ionization equilibrium, a balance is established between the process of ionization and its reverse, recombination, in which a free electron e − and proton p recombine to form neutral atomic hydrogen H, releasing one or more photons γ : e − + p ↔ H + γ The recombination...

Suppose a candidate running for sheriff in a rural community claims that he will reduce the average speed of emergency response to less than 30 minutes (30 minutes is thought to be the average response time, µ = 30 with the current sheriff). Thanks to his campaign promise, he is elected sheriff and keeps careful records of response times. Since the sheriff was elected, there have been 9 emergency calls (N = 9) with a mean response time of 15...
