E.1.4—Atomic transitions Topic Practice
E.1.4—Atomic transitions Topic Practice
Practise using atomic transition diagrams to decide which jumps emit photons and which energy gaps give the highest or lowest λ or f.
How this is tested
- compare transitions on a level diagram to choose the photon with shortest λ or highest f from the largest ΔE
- calculate the largest emitted wavelength from a chosen transition using λ = hc/ΔE after selecting the smallest ΔE
- count distinct emitted wavelengths when an electron can fall through several levels to the ground state
