Difference between Diffraction and Interference

WebDec 2, 2024 · Diffraction occurs at single edges. A slit is nothing more than two separate edges. Each edge creates its own diffraction pattern on the screen, and the closer the edges are to each other the more the two patterns overlap. The further the edges are away from each other the less they overlap. The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc. This principle can be extended to engineer a grating with a structure such that it will produce any diffraction pattern desired; the hologram on a credit card is an example.

WebApr 13, 2024 · We can define two distinct types of diffraction: (a) Fresnel diffraction is produced when light from a point source meets an obstacle, the waves are spherical and the pattern observed is a fringed image of the object. (b) Fraunhofer diffraction occurs with plane wave-fronts with the object effectively at infinity.
