All right, I have to calculate the uncertainty of the grating constant (k=1/d).(adsbygoogle = window.adsbygoogle || []).push({});

I know that the standard deviation of my 14 values of d(spacing bewtween 2 slits in a diffraction grating) is ± 5.031x10-16 m.

Average d = 3.403x10-6m .

k= 2.939x105lines/m.

How would I find uncertainty? 1/± 5.031x10-16 m?

Im really stuck here, please help.

Thank you.
