Diffraction: It is the phenomenon of bending of light around the corners and spreading into the geometrical shadow of a tiny object. Fraunhofer Diffraction: It is a type of diffraction in which source of light and screen are at effectively at infinite distance from the obstacle which causes diffraction. It can be achieved by two convex lens (i) one to make light from source to be parallel (ii) other to focus the light after diffraction on the screen. read less
