lmagine an alternate universe where the mass of the electron is 2.4 times larger than in our universe.Assuming that none of the other properties of the universe are changed, what would be the wavelength of the first line (the line with the longest wavelength)in the Lyman series of the hydrogen atom? Give your answer in nm.
You are studying a very distant quasar and are trying to determine how far away it is. The quasar is
a very bright point-like light source, and there is only one relevant distance measuring technique
applicable to objects at such a great distance. From a spectra of the quasar, you observe that it's
Lyman alpha emission line (which would be at 121.6 nm in a laboratory sample of Hydrogen) is at
130 nm.
What is the distance to this quasar in units of Mpc.
[Hint: Think about what distance measuring technique we use for the very farthest objects in the
universe. You will need to look up a special constant (who's value is uncertain) to complete this
problem. The answer accounts for the possible range of uncertainty in the quantity you need to
look up.]
