What are the key differences between Rayleigh scattering and Mie scattering in the context of atmospheric phenomena?

Rayleigh scattering occurs when particles are much smaller than the wavelength of light, causing shorter wavelengths (blue light) to scatter more. Mie scattering happens when particles are similar in size to the wavelength of light, causing all wavelengths to scatter equally. In the atmosphere, Rayleigh scattering is responsible for the blue color of the sky and the red colors of sunrise and sunset, while Mie scattering is more prominent in hazy or polluted conditions.
