So I know resolving power is given by :
Resolvance = λ/Δλ = nN
Where n = order of fringe being observed and N is the no. of slits.
So I was thinking there are a few ways of increasing resolvance :
1.) Decrease the slit width
2.) Increase the order of the fringe we observe.
3.) Increase the number of slits.
However, wouldn't the first option cause a decrease in transmitted light and hence wouldn't our spectra have decreasing intensity ?
Also, for the second option, it is known that intensity of maximas decreases quite quickly from one order to the next... Hence, would our peak have poor intensity as well ?
