A few clarifying questions about when an electron transitions quantum levels. When they transition to a lower level, do electrons decrease the energy of an electron? Does that decrease in energy for the electrons increase the frequency of light emitted?
When the electron transitions to a lower level, the electron emits energy as a photon, so yes, it does decrease so to say. It becomes more negative. I think the frequency must decrease as well because it is directly proportional to the change in energy. The equation E=hv (h=constant and v=frequency) shows that if the energy decreases, then so does the frequency since h is Planck's constant.
If you think of the concept that energy is neither created or destroyed, the release of the light reflects a decrease in energy for the atom as a whole. The further the gap between the starting and final energy levels does impact the frequency of the light emitted, thus allowing us to analyze the various colors emitted by excited atoms/their electrons. So an atom with an electron dropping from level 4 to level 3 will emit a lower frequency than an atom with an electron dropping from level 4 to level 1 respectively.
