Calculate the energy of a photon emitted when an electron in a hydrogen atom relaxes from n=5 to n=3?
1 Answer
The energy is
Explanation:
You can use the Rydberg formula to calculate the change in energy.
Rydberg's original formula was in terms of wavelengths, but we can rewrite it to have the units of energy.
The formula then becomes
#color(blue)(bar(ul(|color(white)(a/a) ΔE = R(1/n_text(f)^2 - 1/n_text(i)^2)color(white)(a/a)|)))" "#
