### rydberg equation

in the rydberg equation En= (-hR)/(n^2) why is there a negative included?

### Re: rydberg equation

When calculating using quantum levels, the reference or starting point En=0 occurs when n = infinity. This means that all other energy levels (n=1,2,3,...) are below the starting point, and therefore negative.
