Last week Long Islanders experienced blustery weather with a fog adversary in effect. The stormy weather created major air travel delays. Visibility was cut one mile or less at a time. On April 21st,any got a pleasant surprise when the storm lifted. Long Islanders were treated to a quadruple rainbow, considered a rarity when the single rainbow is considered typical. In 250 years, only four multiple rainbows were seen. Many people had to take out their cameras and photograph these phenomena for posterity. Rainbows are very real. Everyone can see them, but they are a type of prism.
Rainbows are a reflection of light coming through droplets of water. While observers can only see an arc, rainbows can be the shape of an entire circle. A rainbow is much like a mirage. The closer you get to a rainbow, the further away it gets, as Dr. Walden gladly points out. Rainbows aren’t only caused by rain, but by many types of water including mist and dew. Rainbows can be seen the western sky in the morning hours and in the early evening, people in the eastern part of the country can see them. There are many showers in Hawaii, which means many chances to see rainbows.
Multiple rainbows happen when sunlight bounces more than once off water droplets. It inverts the order of the colors. With multiple rainbows, they get fainter and fainter with each new rainbow.
