- Diffraction is used a lot in discovering the structures of materials and atoms.
- It has been used a lot in discovering medicines and drugs.
- Diffraction is also fundamental in other applications such as x-ray diffraction studies of crystals and holography* {} DAY TO DAY APPLICATION*
The effects of diffraction are usually seen in everyday life. One of the most evident examples of diffraction are those involving light; for example,when you take a keen look at a CD or DVD the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern. This principle can be extended to engineer a grating with a structure such that it will produce any diffraction pattern desired;

2.It's Application is also imminent in fibre optic communication (wavelength division multiplexing, to be more specific, which allows different wavelengths of light to carry different signals over a single strand of the optical fibre).
3.Hologram (holos--whole: gram-gram -message) can be imagined as a complicated diffraction grating. The recording of a hologram involves the mixing of a laser beam and the unfocused diffraction pattern of some object. In order to reconstruct an image of the object (holography is also known as wavefront reconstruction) an illuminating beam is diffracted by plane surfaces within the hologram, following Bragg's Law, such that an observer can view the image with all of its three-dimensional detail.
