(2) Anelectron in the following states of hydrogen decays by a sequence of electric dipole (E1) transitions to the ground state 100: 1 (i) Electron initially in n = 3, l = 0, m = 0 state. (ii) Electron initially in n = 3, l = 1, m = 0 state. What decay routes to the ground state 100 are open to it? Assume gross structure eigenfunctions of energy nlm, and for each initial state specify the routes in the following way 300 nlm nlm 100

Question 3 1 pts A group notices that the capacitor is not getting enough time to charge all the way like they need to take data. They decide to change the "Sec/Div" knob on the Oscope to fix this problem. Could this improve the situation for the capacitor. No, changes to the Oscope cannot change anything about the circuit it is measuring (assuming the Oscope is not broken). No, the group needs to change the "Volts/Div" knob to fill the capacitor faster. Yes, the "Sec/Div" knob controls how time is displayed on the Oscope. Question 4 1 pts A group is trying to make a lightbulb flash with a function generator. They think the lightbulb should be flashing, however the lightbulb is continuously on. They have measured following voltage across the lightbulb. What is the problem? Maybe the light bulb has blown this is why the group is not getting the expected behaviour. The voltage change on the lightbulb is too small. Maybe the bulb is becoming dimmer and the group doesn't notice this small change. When the voltage decreases, it becomes negative without changing magnitude. This flips the direction of the current, but does not decrease the current. Their must be a wiring problem. The Oscope clearly shows the lightbulb should be turning on and off.
