Q. Define: grating element.
The combined width of a slit as well as a ruling in a plane diffraction grating is called as a grating element.
Two grating A and B have the same width of the ruled surface but A has greater number of lines. Giving reasons compare in two cases (a) Intensity (b) Width of principal maxim
