Natural Phenomenon: Rainbows

Rainbows, appearing during rainfall or right after the rain stops, are a beautiful though fairly rare optical and meteorological phenomena. A rainbow does not exist in a particular location in the sky or at a spesific distance, but comes from any water droplets viewed from a certain angle relative to the sun's rays. The rainbow's apparent position depends on observer's location and the position of the sun. All raindrops refract and reflact the sunlight in the same way, but only the light from some raindrops reaches the observer's eye. This light is what constitutes the rainbow for the observer. In locations that receive more rain, rainbows may be more common, since rainbows are merely caused by the reflection, refraction, and dispersion of light inside water droplets into the full spectrum of the light in the sky, often set against the backdrop of darker storm clouds, which in turn highlights the rain droplets directing and scattering light and so shining bright inside the rainbow arc. Rainbows are always observed opposite the sun with no exception.
