Frequency Equations

Postby alanaarchbold » Sat Oct 13, 2018 2:54 pm

I know some people were saying that there's an equation that combines E=(-hR)/(n^2) and E=hV. Does anyone know what it is?

You might be talking about the equation that combines E=hv with c=λv. Substitute v to get E=hc/λ.

The textbook gives us the Rydberg formula, which is
So I think it has to have something to do with combining the equations E=hv, and E=-hR/n^2 , so you get v=-R/n^2. Then, if you were trying to find v1-v2, you would get
However, this leaves you with -R in the equation, unlike the Rydberg formula, so I'm still a bit confused too.
