What is an inverse meter?

Hi,
I'm doing some astronomy work and one problem involves using Rydberg's constant. However, it is inverse meters and I'm confused. Does that mean that it is 1/109737361.6 m? Thanks.

Yes - it just means per metre.

Okay so if I have the 1/lambda = R (1/nf^2 - 1/ni^2) equation, how would I go about plugging it in? Is it any different than plugging in any other numbers?

after you multiply R by the fraction,
you probably want to reciprocate the result (1/x)
to obtain the wavelength.
