Question 1.15 6th Edition

Postby Sydni Stewart » Mon Oct 22, 2018 8:47 pm

Question: 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.

How do we know that n1 is equal to 1?

The Lyman series for the hydrogen atom is known to lie in the ultraviolet spectrum and its principle quantum energy level is n1=1, so for this problem since the line is observed in the ultraviolet spectrum, you can apply the fact that the Lyman series is n1=1.
