Rayleighin

Rayleighin is a term that appears to be a misspelling or a phonetic rendering of "Rayleigh". The Rayleigh scattering phenomenon is named after the 19th-century British physicist Lord Rayleigh. Rayleigh scattering describes the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. This occurs, for example, when light from the sun interacts with the atmosphere. The sky appears blue during the day because blue light is scattered more effectively than red light by the gas molecules in the Earth's atmosphere. Similarly, sunsets and sunrises often appear red or orange because the sunlight has to travel through more atmosphere, and the blue light has been scattered away, leaving the longer wavelengths to be seen. This principle has applications in various fields, including atmospheric physics, remote sensing, and the study of interstellar dust. The mathematical description of Rayleigh scattering depends on the size and properties of the scattering particles and the wavelength of the incident radiation.
