Initial and Final Energy Levels

Postby Sandeep Gurram 2E » Thu Oct 01, 2015 11:58 pm

Question (1.15): In the UV 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.

I understand that you first have to use the λν = c formula to calculate frequency and then use Bohr's frequency condition to find the initial and final energy levels. However, I am confused as to why the initial energy level n1 must be 1. In the solutions manual it was considered a given that the initial energy level was 1. Is there a context clue in the question suggesting that the n1 must be 1?

The fact that the emission is UV tells that it is in the Lyman series and thus n2=1
