Rayleigh scattering

Rayleigh scattering is the phenomenon responsible for the scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light. It explains why the sky appears blue during the day and reddish during sunrise and sunset. This effect occurs because shorter wavelengths of light, like blue and violet, are scattered more efficiently than longer wavelengths. Understanding Rayleigh scattering is essential in fields such as atmospheric science, optics, and astronomy.
