Scattering vs Reflection
Reflection and scattering are two phenomena observed in many systems. Reflection is the process of diversion of a path of a particle or a wave due to a non-interacting collision. Scattering is a process where interaction between the two colliding particles occurs. Both of these phenomena are very important in fields such as mechanics, geometrical optics, physical optics, relativity, quantum physics and various other fields. It is vital to have a thorough knowledge in reflection and scattering in order to excel in such fields. In this article, we are going to discuss what reflection and scattering are, their definitions, the similarities between reflection and scattering, their application, and finally the differences between reflection and scattering.
What is Scattering?
Scattering is a process which plays a very important role in many fields of physics and chemistry. Scattering is the process where waves get deviated due to certain anomalies in the space. Forms of radiation such as light, sound and even small particles can be scattered. The cause of scattering can be a particle, a density anomaly or even a surface anomaly. Scattering can be considered as an interaction between two particles. This is very important in proving the wave particle duality of light. For this proof, the Compton Effect is taken. The reason for the sky being blue is also due to scattering. This is due to the phenomenon called the Rayleigh scattering. The Rayleigh scattering causes the blue light from the sun to be scattered more than other wavelengths. Due to this, the color of the sky is blue. Other forms of scattering are Mie scattering, Brillouin scattering, Raman scattering and inelastic X-ray scattering
什么是反思?
反射是一种主要在光学中讨论的现象,但反射在其他各个领域也有应用。对于光,反射主要受到的法律的控制,即入射角等于任何给定点的反射角度。角度相对于反射表面的反射点时的正常绘制。有些表面完全反映了入射光,而有些表面则部分反映了入射光。我们的愿景主要由反思支配。我们看到的大多数对象都被它们反射的光所看到。对于这些表面中的每一个,每个波长的反射率都不同,从而为表面提供了独特的颜色和纹理。反射不是波性质。诸如电子之类的颗粒也显示出反射。反射被认为是物质的粒子特性。
反射和散射有什么区别? • Scattering is a wave property of matter whereas reflection is a particle property. • Scattering requires a total absorption and emission of a particle or a photon, whereas reflection only bounces back the incident particle or wave. • The wavelength of the incident wave can change due to scattering, but it cannot change due to reflection. • Reflection is easily observable, whereas observation of scattering requires advanced equipment. • The low of reflection holds to any reflective material whereas the equations for scattering is dependent on the materials and conditions used. |
