Why in the Rydberg equation does the formula 1/y = R (1/ni^2 - 1/nf^2) some people change the initial and final energy levels depending on different questions? Some questions use nf - ni in the equation, while other questions use ni-nf instead. Does it have to do with emission/ absorption? How would you know when to use which? Thank you.
