$example of diffraction of a wave$

We describe a hologram as a rather complicated diffraction pattern.We apply the same ideas to the three-dimensional example of x-ray diffraction from crystals.It is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. We show how periodic patterns lead to sharp diffraction patterns, and discuss the example of the diffraction grating in detail. Diffraction is normally taken to refer to various phenomena which occur when a wave encounters an obstacle.We prove a useful result, the convolution theorem, for combining Fourier transforms.We apply these techniques to examples involving beams made with one or more slits and rectangular regions. The meaning of DIFFRACTION is a modification which light undergoes especially in passing by the edges of opaque bodies or through narrow openings and in which the rays appear to be deflected also : a similar modification of other waves (such as sound waves) or of moving particles (such as electrons).We show how the integral simplifies in two extreme regions - very close to the source of the beam, where it really looks like a beam - and very far away, where diffraction takes over and the intensity of the wave is related to a Fourier transform of the wave pattern at the source, the same result that we found in our heuristic discussion of interference.We find the relevant boundary condition at infinity and express the solution in the form of an integral. The laser light is diffracted as they pass through the slits. Diffraction is the spreading of light at openings and edges while interference is the process by which light waves travelling in same medium combines to produce a new wave. We show the connection with making a beam. The wave nature of light can be demonstrated through diffraction and interference. We then continue our quantitative analysis of interference and diffraction by discussing the general problem again as a forced oscillation problem.We give a heuristic discussion of the physics, and generalize it to get the fundamental result of Fourier optics. This is the classic example of interference. While the diffraction is an edge phenomenon, where the wave hits the corner of the obstacle, which is placed in the path of the propagation of the wave, and then. We begin by discussing interference from a double slit. Refraction is a bulk phenomenon it occurs when the wave hits a surface and travels through the bulk of another medium of different densities, and the bending of the wave takes place.In this chapter, we show how the phenomena of interference and diffraction arise from the physics of the forced oscillation problem and the mathematics of Fourier transformation.
