a. How much energy does an electron in the n=1 (lowest-energy) state of Hydrogen have? Repeat for n=2 and n=3.
b. How much energy is emitted if an electron in the n=3 state transitions to the n=2 state?
c. We used diffraction gratings in class that had 500 lines/mm (white cardboard surrounding grating) and 1000 lines/mm (rainbow cardboard surrounding grating). For the 1000 lines/mm grating, what are the angles of emitted light (relative to the central maximum) when an n=3 to n=2 electron transition occurs in Hydrogen?

How much energy is required to cause an electron in hydrogen to move from the n = 3 state to the n = 2 state? b) If the electrons gain this energy by collision between hydrogen atoms in a high temperature gas, calculate the minimum temperature of the heated hydrogen gas. The thermal energy of the heated atoms is given by 3kBT/2, where kB is the Boltzmann constant.
