Sphere extinction
WebTo find the amount of extinction in a drop of a particular size, we shall utilize theory of scattering that we have learnt in Chapter 3, for the case when an electromagnetic wave passes through a material medium.Recall that, while discussing Mie scattering theory, we derived quantitatively the amount of wave power scattered and absorbed from the … WebThe term “extinction” means the loss of light in the atmosphere from a directly transmitted beam. Two different mechanisms contribute to extinction: absorptionand scattering. …
