	Diffraction effects occur when waves interact with objects having a size similar to the wavelength of radiation. Diffraction is not important for optical fibers because there must be some specific order in the materials in order to have a diffraction pattern. And optical fibers are deliberately made from amorphous solids or glasses.		Diffraction effects occur when waves interact with objects having a size similar to the wavelength of radiation.

	If white light is diffracted, each λ will be diffracted through a slightly different angle. Red light is diffracted through a wider angle than violet light because sin θ is related to wavelength.

	The grooves can be formed by photochemical reactions that leads to the displacement of the materials on the surfaces forming grooves. This is interesting because these patterns can be used to store information.
