Webomy as either incoherent or coherent scattering (van de Hulst, 1981; Bohren and Huffman, 1983). Incoher-ent and coherent scattering differ in whether the be-havior of scattered light is independent of or dependent upon the phases of scattered light waves, and in wheth-er the phases of scattered wave can be ignored or must WebIncoherent light scattering. In the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects.

WebAn incandescent light bulb is an example of very incoherent source. We can produce coherent light from an incoherent source if we are willing to throw away a lot of the light. We do this by first spatially filtering the light from … WebJan 30, 2024 · Coherent waves are waves that have the same frequency and waveform. In simpler words, they are identical waves. Two waves from the same source are coherent. There may exist some phase differences due to path differences when they superimpose.
