Which statement about the visible line emission spectrum of atomic hydrogen is correct?
A. The lines are equally spaced because the energy levels are equally spaced
B. The lines get closer together towards longer wavelength because the energy levels converge as n increases
C. The lines get closer together towards higher frequency because the energy levels converge as n increases
D. The lines merge into a continuous band because the electron can take any energy

Odpowiedź z klucza
C ✔
«the energy levels converge as n increases, so the lines get closer together towards higher frequency (shorter wavelength)»
Schemat punktowania
1 mark for the correct option.
Komentarz
Frequency and wavelength are inversely related: lines converging towards higher frequency converge towards shorter wavelength.
