The formula applied in diffraction gratings is:
dsin(θ) = nλ
d is the distance between two adjacent openings in the grating,
θ is the angle between two minima or maxima of light
n is the order of the maxima or minima formed.
λ is the wavelength of the light that is diffracted.
When light waves pass near a barrier they tend to bend around that barrier and become spread out.
The definition of diffraction is the spreading of waves as they pass through or around an obstacle.
More specifically when applied to light, diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light’s wavelength.
