An excited hydrogen atom emits light with a frequency of 1.14*10^14 Hz to reach the energy level for which n=4. In what principle quantum level did the electron begin?
I've attempted to attack the question in several different ways, like finding the energy and rydeberg equation. please HELP

Looks like you are on a roll.  Write down the Rydberg equation, and think about what you have been given.

1.14*10^12Hz=(3.29*10^15) {1/16-1/n} 
would this be correct ? If so I still can't figure out how to get n which is probably basic math I can not remember.
