Question number 1.15

Postby Natalie Yakobian » Tue Sep 29, 2015 6:39 pm

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.

For this question I was able to find the two energy level by trail and error after finding the V and the dividing V by R.

Is there another way?

You can identify the series as a Lyman series based on the fact that you are seeing ultraviolet light (page 7 in the textbook). For a Lyman series, n1=1 so you would only have to calculate n2. Similarly, for a Balmer series, n1=2.
