That I know, but what number corresponds to the series limit? Some places said 14, others said 12, and others infinity. I'm not sure how to use infinity in a calculation though.
Hi. I'm having some trouble calculating the wavelength for series limit for the Paschen series.
I've set the Rydberg equation up with 1/(n sub f squared) as 1/(3 squared), but I'm not sure what goes in for 1/(n sub i squared) as the initial position.
I'd appreciate any help. Thanks!
