What are Diffraction Gratings & Diffraction Uses?

WebSpectral Resolution. The resolution is the ability to separate wavelengths. It is usually expressed as the Full Width Half Maximum (FWHM). The resolution can be theoretically determined by multiplying the reciprocal dispersion of the grating by the slit width.
