A ground state hydrogen atom absorbs a photon of light having a wavelength of 93.03 nm. It then gives off a photon having a wavelength of 1005 nm. What is the final state of the hydrogen atom?

Question

What is the equation to solve this?

Answer 1

find the energy of 93.03 nm

E=plancksconstant*speedlight/lambda

Next, add that to ground state energy (look it up)

then find the energy of the emitted photon as above, then
you have the final energy state.

finalenergystat=groundstate/n^2
solve for n
