### Atomic Spectra Video Module Question

Posted:

**Thu Oct 06, 2016 2:59 am**Hi, could anyone help me with this question? I'm not sure if I'm messing it up, but every time I try to solve it using our formula (not the version from the textbook), I always seem to get a decimal answer around 3.2.

An excited hydrogen atom emits light with a frequency of 1.14 x 10^14 Hz to reach the energy level n = 4. In what principle quantum level did the electron begin?

Thanks in advance!
