Question

Quizplus · Accepted Answer

Red wavelengths bend the least compared to other colors in the visible spectrum when passing through ice crystals, and as a result, red appears on the inside edge of halos or sundogs. This is due to the dispersion of light, where different wavelengths of light are bent by different amounts, with shorter wavelengths (blue) bending more than longer wavelengths (red).
