Rayleigh jeans law in terms of wavelength

WebJun 24, 2024 · However, the MW region has become important in surface remote sensing owing to its long wavelength that can penetrate clouds and is affected less by the atmosphere. MW surface emissivity has a significant role in the global weather forecasting system and is needed to assimilate the MW radiation data of various satellites [ 16 , 17 ]. WebRayleigh scattering (/ ˈ r eɪ l i / RAY-lee), named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle …
