Hello there, a question that I have been given is to "find the wavelenght of light emitted from an electron jumping from the 2nd to the 6th orbital (or vise versa if that matters). The atom is hydrogen"

2. Relevant equations

[itex]E= \frac{hc}{λ}[/itex]

3. The attempt at a solution

I've already worked out this question using the Rydberg Formula where I got 410 nm (which I know is correct because I crossed checked it using wikipedia and my text book). However, this is part of a quatumn mechanics assignment, and I was suppose to use the forumla [itex]E= \frac{hc}{λ}[/itex]

But I have no idea about how to apply the forumla to get the wavelenght. But if I made [itex]λ[/itex] the subject, it would read to be

[itex]\frac{hc}{E} = λ[/itex]

I think what I need to find out is the value of E (well, obviously thats what I need to find). But how do I relate the different energy levels with the orbials in which the electron travels?

Surely its not just 6 -2 = 4 :tongue:

thanks - miniradman
