### Investigating Atoms: Topic 1A Problem 1A.15

Problem 1A.15 states:
In the ultraviolet spectrum of atomic hydrogen, a line is observed at 102.6 nm. Determine the values of "n" for the initial and final energy levels of the electron during the emission of energy that leads to this spectral line.

which equation would you use to go about solving this problem? Is it more beneficial to use En= -hR/n^2 or the one from the book; v=R{1/n1^2 + 1/n2^2} ?

I used the second equation you listed that was shown in the book. This method was more efficient to me.
