چکیده
Diffraction gratings are used inmany fields in physics, especially astronomy. In astronomy, diffraction gratings are used in spectrographs to analyze the light of astronomical objects that is gathered by telescopes. These gratings use the principles of constructive and destructive interference of light to spread the different wavelengths out based on the wave nature of light and the diffraction grating equation, Eq. 1, where d is the grating spacing, θ is the angle of the incoming light, n is diffraction order, and λ is the wavelength of light.
