2 pts Clouds appear white because…

○ a. Non-selective scattering — water droplets ≫ wavelength, all wavelengths scattered equally
○ b. Rayleigh scattering favors blue
○ c. Mie scattering affects only IR
○ d. Clouds absorb all visible light

Reveal answer

Correct: Non-selective scattering — water droplets ≫ wavelength, all wavelengths scattered equally

Model answer

B, G, R scattered in equal proportion → white.

💡

'Non-selective' literally means ALL colors treated equally → white. Big particles (droplets) = non-selective. Tiny particles (molecules) = Rayleigh = blue sky.
