### Rydberg formula

I'm confused about the Rydberg formula for calculating the wavelength/frequency of light emitted as a hydrogen electron changes energy levels. In the textbook, it is defined as v (frequency) = R(1/n12 - 1/n22). However, when I looked online for more information, almost every online source replaced v with 1/wavelength. I am confused, since this doesn't seem to be equivalent. Shouldn't v be replaced with c/wavelength?

### Re: Rydberg formula

I would use that equation to calculate frequency and then from there stick with v=c/λ or λ=c/v to determine wavelength.
