Arnold makes a chart to summarize what happens when light interacts with matter and is reflected.



Which idea does Arnold need to correct?

In specular reflection, reflected rays move in the same direction.
In scattering, light strikes particles in the atmosphere.
In diffuse reflection, reflected rays move in different directions.
In scattering, long wavelengths are scattered the most.

The incorrect idea is: "In scattering, long wavelengths are scattered the most."

Correction/explanation: For the common case of Rayleigh scattering (particles much smaller than the wavelength), short wavelengths are scattered far more strongly — intensity ∝ 1/λ^4 — which is why the sky appears blue. (Larger particles produce Mie scattering, which is less wavelength‑dependent.)
