Why do clouds appear white? |
| Answer» UDS are WHITE because, luckily for us, the water droplets reflect all the frequencies of the visible LIGHT. And when you see a dark cloud, it is simply its shadow you see, as thick clouds doesn’t allow much light to go through.While on the subject, we often say that a dark cloud is a cloud heavy with rain. Well, it is the opposite; the specific gravity of a MOLECULE of water is less than that of nitrogen and oxygen. ( 1.18 for air and 1.0 for water). | |
