This phenomenon is most widely used in the determination of the distance between two consecutive atoms of an element. The x-ray tube and detector move in a synchronized motion, the observed signal is then recorded and studied. In x-ray diffraction, the sample is kept in an instrument and is illuminated with x-rays. The next time you see such a stunning view, you can share the reason behind it. This deflection of light, due to the presence of a barrier in its normal pathway, is nothing but diffraction. When the light rays from the sun try to reach the ground but are blocked by the clouds, the light waves get diffracted and deviated. These magnificent looking rays are known as crepuscular rays or God rays. You must have seen this breathtaking view for at least once in your life. This bending, undoubtedly, is known as diffraction. The door acts as an obstacle in the path of light, therefore the light bends. Suppose, there is a room with no light source, plus the light from the door is forbidden to enter the room as it is closed, and when someone opens the door partially, you can observe that the light gushes inside with a bend across the edges and around the corners of the door. Finally, providing us with a 3-Dimensional experience. This pattern is then made to fall on the holographic plate. Different versions of the image get diffracted and reach the lens from multiple sides, all together forming an interference pattern. Hologram basically makes use of diffraction to generate a 3D impression of the image. It is one fine technology that promises us an incredible future. Hologram, the word has been derived from two Greek words, ‘holo’ means whole, and ‘gram’ means a message. This is the reason why we see a rainbow-like pattern on a compact disk. When light falls on the top of a CD, a part of it gets diffracted while some part of the light gets reflected. The surface of the compact disk is shiny and consists of a number of grooves. Compact Disks are most susceptible to the process of diffraction.
