camp. Most scientists have suggested that the size of the raindrops shape how they reflect light and what the rainbow will look like. Others have said that it depends where the raindrops are—since a low-lying haze of water will reflect at a different angle than a high shower of drops. ...
Understanding droplet formation in pure water in a controlled lab setting is challenging enough, but in the atmosphere,dropletsform in the presence of many other substances. Some of them, like nitrogen, oxygen and argon, do not interact much with water and are easy to account for. The complica...
