A hydrogen atom in the ground state absorbs a photon whose wavelength is 95.0 nm. The resulting excited atom then emits a photon of 1282 nm. What are the regions of the electromagnetic spectrum for the radiations involved in these transitions? What is the principal quantum number of the final state resulting from the emission from the excited atom. 6.

Answer:
The absorption of a photon by hydrogen atom takes place from ground state to the final state.
The wavelength () of the transition for hydrogen like species is given by the equation:
Here, is Rydberg’s constant
h is planck’s constant =
c is speed of light =
We have wavelength of photon absorbed by hydrogen atom,
Calculate the final state for absorption by putting the known values in the above expression:
In case of absorption the electron moves from to.
