SUMMARY

The significance of inverse meters in astronomy calculations is crucial for understanding Rydberg's constant, which is valued at 1/109737361.6 m. In the equation 1/lambda = R (1/nf^2 - 1/ni^2), the inverse meter indicates that Rydberg's constant is expressed in terms of per meter. To find the wavelength, one must multiply R by the fraction derived from the energy levels and then reciprocate the result to obtain the wavelength.

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.
