|---|---|---|---|
| Rayleigh scattering | Sunlight is scattered by atmospheric molecules, with blue light scattering the strongest | common cumulus clouds | clear day |
| Mie scattering | Larger particles scatter light of all wavelengths | altostratus clouds | cloudy weather |
| Diffraction phenomenon | Light passing around the edges of cloud droplets produces dispersion | colorful clouds | Thin clouds and strong sunshine |
| refraction reflection | Light is refracted in ice crystals | cirrus | high altitude areas |
