1. The problem statement, all variables and given/known data Electron on n=6 level emits wavelength of 410.2nm. What energy level does it move too? 2. Relevant equations 1/L = R ( 1/N^2 - 1/n^2) where N is initial and n final R=1.096779*10^7 m 3. The attempt at a solution 1/410.2 = 10967790 (1/36 - 1/n^2) 1/4498975152 = (1/36 - 1/n^2) -1/36 -1/36 4498975152 =n^2 sqrt n=67074...... this number is wrong, it is not an energy level, and not one of the answers, what did I do wrong?
