when electron makes a transition, between state with energy Ei to another state with energy Ef, the frequency \nu of the emitted or absorbed photon is: \[\Large h\nu = Ef - Ei\]
Michele_Laino
  • Michele_Laino
more precisely: \[\Large h\nu = \left| {Ef - Ei} \right|\]
Michele_Laino
  • Michele_Laino
since we have considered the case of absorption of a photon

now we have: \[\Large \nu = \frac{c}{\lambda }\] so we can write: \[\Large \frac{{hc}}{\lambda } = \left| {Ef - Ei} \right|\] or: \[\Large \lambda = \frac{{hc}}{{\left| {Ef - Ei} \right|}}\]

now the greatest wavelength corresponds to the smallest energy change
Michele_Laino
  • Michele_Laino
and the smallest energy change, happens when electron jumps the smallest number of levels

Electron jumps from fourth orbit to first orbit.
Michele_Laino
  • Michele_Laino
no, since the electron makes three transitions
Michele_Laino
  • Michele_Laino
I think when electron makes only one transition, do you see that option?
Michele_Laino
  • Michele_Laino
for example in the first option the electron goes from the third level to the second one

Whats the answer
Michele_Laino
  • Michele_Laino
so it makes only one transition, right?
anonymous
  • anonymous
yeah
Michele_Laino
  • Michele_Laino
therefore it is the first option
