Question

Calculate the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen. (Hint: on the Energy Levels For Hydrogen chart, how much energy is required to ionize an n = 1 electron?) Keep 3 significant figures in each of your sub answers and in your final answer as you work through this problem.

Answer 1

Do you know the ionization energy for hydrogen?

If you do, then we can relate the energy to the wavelength for a photon:
\[E = h \nu =\frac{hc}{\lambda}\]with\[\nu = frequency,\lambda=wavelength\]

Answer 2

and h is Planck's constant

Answer 3

okay thank you
