Question

how the grating is prepared​

Answer 1

Explanation:

An idealised grating is made up of a set of slits of spacing d, that must be wider than the wavelength of interest to cause diffraction. ... After light interacts with the grating, the diffracted light is composed of the sum of interfering wave components emanating from each slit in the grating.
