Question

1. What is the energy in eV and wavelength in µm of a photon that, when absorbed by a hydrogen atom, could cause a transition from the n= 4 to the n= 8 energy level?

a) energy in eV

b) wavelength in µm

2. The so-called Lyman-αphoton is the lowest energy photon in the Lyman series of hydrogen and results from an electron transitioning from the n= 2 to the n= 1 energy level. Determine the energy in eV and the wavelength in nm of a Lyman-αphoton.

a) the energy in eV

b) the wavelength in nm
