Describe some practical applications of diffrac... - SS2 Physics Optics - Wave Optics Question

Diffraction of light waves finds numerous practical applications in various fields. One such application is in the design of optical devices such as diffraction gratings and holograms. Diffraction gratings consist of a series of closely spaced parallel slits or rulings that cause light waves to diffract and interfere, producing a pattern of bright and dark spots. They are used in spectroscopy to separate light into its constituent wavelengths and in optical instruments to disperse light for analysis.

Holography is another application of diffraction where interference patterns are recorded on a photographic medium. These recorded interference patterns produce three-dimensional images when illuminated by coherent light, creating realistic and detailed representations of objects. Holography has applications in security, data storage, and art.

Diffraction is also utilised in particle size analysis techniques such as laser diffraction. By passing a laser beam through a dispersed.
