PRACTICE / Hydrogen spectrum
Use energy gaps before naming spectral lines
In the hydrogen model En = −13.6 eV/n², compare the emitted photons for transitions 4 → 2 and 3 → 2.
What is λ4→2 divided by λ3→2?
Organize the givens & assumptions
- En = −13.6 eV/n²
- Transitions end at n = 2
- λ = hc/Ephoton
Isolated hydrogen, stated nonrelativistic energy-level model, photon recoil and fine structure neglected; each transition emits one photon.
