(Source: www.deltatech.com/rainbowx) People have been asking questions about rainbows since the beginning of time. One question frequently asked is-- How far away is that rainbow? The rainbow's distance extends from the nearest to the farthest rain drops that contribute any part of the colored light. The closest of these raindrops may be miles away. In the case of water spray from a lawn sprinkler in which a Rainbow appears, you can reach right in and "touch it" . . . or so it seems. Do two people ever see the same Rainbow? No! As the eyes of two people cannot occupy the same place in space at the same time, each observer sees a different Rainbow. Why? Well, because the raindrops are constantly in motion so its appearance is always changing. Each time you see a rainbow, it is unique in its own spectacular way! The rainbow is divided into bands displaying the different colors of the spectrum. The colors are formed by the refraction and reflection of the sun's rays in drops of rain. The higher we are above the ground, the more of the Rainbow we can see. Many people consider rainbows to be an omen of some kind. The legends of many cultures see the rainbow as a kind of bridge between heaven and earth. One of the most beautiful sites in nature, the rainbow has become in Western culture, a symbol of renewed hope - something lucky to look upon. |
