A) the energy of revolution of the electron in its lowest energy orbit divided by h.
B) the energy gained by the electron divided by h.
C) the energy lost by the electron divided by h.
D) the energy of revolution of the electron in its highest energy orbit divided by h.

Quizplus · Accepted Answer

The frequency of light emitted when an atom makes a transition is equal to the energy lost by the electron divided by Planck's constant (h), according to the equation E = hf, where E is the energy difference between the two states, h is Planck's constant, and f is the frequency of the emitted light.

If H = Planck's Constant, the Frequency of Light Emitted
