Helium monochromatic light

WebThe only thing that I know is that if I use a diffraction grating and the light isn't monochromatic, I'll see maximums of the same order m at different angles, but I also know that if wavelengths are very close I may not see them. I have to mind the resolutive power of the grating ( R = m N ). If N1=1000 lines/mm and N2=500 lines/mm and the ...
