Energy Level Transfer of Hydrogen's electron. For each line, determine the prinicpal energy level to which hydrogen's electron was excited. When the electron fell to the 2nd level, energy was released corresponding to each of the lines.
E= 2.179X10-18 (1/n2 lo- 1/n2 hi). The value for "E" comes from your previous calculation. nlo= (2nd Principal energy level). You are looking for n hi.
