All right, I have to calculate the uncertainty of the grating constant (k=1/d).
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.
