Question

Quizplus · Accepted Answer

The whiteness of clouds primarily involves reflection and refraction of sunlight. Clouds appear white because they reflect and scatter all wavelengths of visible light. When sunlight hits a cloud, the light is scattered by the tiny water droplets and ice crystals that make up the cloud, causing the cloud to appear white. Unlike the blueness of the sky, which is caused by the selective scattering of sunlight by air molecules, the whiteness of clouds is due to the reflection and scattering of sunlight by cloud particles.
