We are asked to find the energy and wavelength for an n1 to n3 transition in hydrogen.
00:14
So let's go ahead and do our wavelength first.
00:20
Or excuse me, let's do our energy first.
00:26
So we'll be using our rydberg constant of 2 .18 times 10 to the minus 18th.
00:40
And i believe that's in joules.
00:44
And i will be using my change in energy is negative of my right -berg constant times one over n final minus 1 over an initial.
00:57
Both of those quantities squared.
01:01
So negative 2 .18 times 10 to the minus 18th joules times one final is 1 over 1 over 1.
01:18
3 squared minus 1 over 1 squared.
01:25
Okay, let me get a calculator out here.
01:37
So i'm going to take my negative 2 .18 times 10 to the negative 18th times parentheses 1 divided by 9 minus 1...
