Example from Summer Test #1, Question 4a

Postby 104785906 » Tue Jul 11, 2017 10:42 pm

In the question, we're told the electron transitions from n=3 to n=1. So, our initial is 3 and final is 1. We should apply the concept, Ef-Ei. I am confused because in the answer, the way it was solved shows ...(1/3^2 - 1/1^2). Why is this?

Because v(frequency)=R[(1/n(1)^2)-(1/n(2)^2)], so v=R[(1/(1)^2)-(1/(3)^2)] and, if multiplied by -h the equation can be rewritten as E=-hR[(1/3^2)-(1/1^2)].
