Rydberg Equation: Physics and Beyond

[Iceking20]

TL;DR

Is Reydberg equation still valid and use?

I saw that rydberg equation used for hydrogen atom,so does it still acceptable for world of physics or it just dinied like bohr model?

Where did you see this?

The Wikipedia article you linked to explains in which cases the formula gives correct results and in which cases it does not.

So what is the way to calculating orbital energy level?

Do you mean for cases where the Rydberg formula does not give correct results? That is a much more complicated subject which cannot be dealt with adequately in a PF discussion thread. You should consult a textbook on QM.
