Sig Figs in Quantum Questions

Postby ssendhil » Tue Oct 13, 2015 12:43 am

Hi everyone, I recently encountered a problem that gave the orbital n values for an electron and asked to find the wavelength. Because the only values given in the question were n=4 and n=5, how do I know how many sig figs to use for my answer?

I believe that in this specific case you would have to look to your given constants to find the right amount of sig figs

I would use either the number of sig. figs. in the constant used or round to the thousandth decimal because it is better to be precise.
