Clouds appear white because of which type of scattering, where the scatterer size is similar to or larger than the wavelength of light?
ARaman scattering
BTyndall scattering
CRayleigh scattering
DMie scattering
Answer & Solution
Correct answer: D. Mie scattering
1. Mie scattering occurs when the scatterer diameter is comparable to or larger than the wavelength.
2. Water droplets in clouds satisfy this condition.
3. In Mie scattering all colours are scattered nearly equally, recombining as white.
4. Rayleigh scattering, by contrast, is wavelength dependent and gives the blue sky.
