RAINBOW

ABOUT RAINBOW:

     Rainbow is a natural phenomenon that happens after Rain. It is one of the most beautiful phenomenon created on earth. A rainbow is a multicolored arc in the sky which appears when sunlight hits water droplets. The magical and wonderful phenomenon of a colorful arc in the sky is known as the rainbow. The seven colors that exist in a rainbow are violet, indigo, blue, green, yellow, orange and red. Rainbows are usually seen on the opposite end of where the sun is located. The Rainbow is a lovable scenery that is colorful and pleasant to eyes. In many Civilizations, rainbows are considered to bring good to society and is a symbol of peace and harmony. Rainbows means peace and harmony in many ancient cultures.  There are two main components by which a rainbow is formed i.e. light and drops of water. The state of Hawaii in America is the only place on earth, where rainbows occur most. When the sun is lower, then the rainbow formed in the sky will be higher. The semicircle formed by rainbow makes a 42-degree angle which starts from the direction opposite to the sun. In simple words, A rainbow is an arc of color in the sky that can be seen when the sun shines through falling rain. The Greeks used to imagine that it was a sign from the gods to foretell war or heavy rain. The Norsemen considered the rainbow as a bridge over which the gods passed from earth to their home in the sky. Others have tried to explain the phenomenon physically.

HOW RAINBOWS ARE FORMED:

     A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths–or color. When light exits the droplet, it makes a rainbow.  A rainbow is caused by three phenomenon of light – reflection, refraction and dispersion.

TYPES OF RAINBOWS:

Some of the different types of rainbows are,

  • SUPERNUMERARY RAINBOWS:

     Supernumerary rainbows are faint bow lines that appear just inside the main rainbow.

  • MULTIPLE RAINBOW:

      Multiple rainbows are another type of rainbow which is also a rare occurrence. Multiple rainbows are sometimes referred to as double rainbows. As the name suggests, multiple rainbows are instances when more than one rainbow occur simultaneously in the same place and are made up of a primary rainbow and other secondary rainbows. 

  • MONOCHROME RAINBOW:

       A red rainbow, also called a monochrome rainbow, usually appears at sunrise or sunset.

  • HIGHER-ORDER RAINBOW:

      Higherorder rainbows appear to viewers facing both toward and away from the sun.

  • LUNAR RAINBOW:

      A moonbow is also commonly referred to as a lunar rainbow. A moonbow is a rare natural atmospheric phenomena that occurs when the Moon’s light is reflected and refracted off water droplets in the air. Moonbows are much fainter than rainbows made by the sun and often appear to be white.

INTERESTING FACTS OF RAINBOWS:

            Some of the interesting facts about rainbows are,

  • A very rare quadruple rainbow was seen over long Island, NY. In April 2015.In the past 250years, only triple and quadruple rainbows have ever been documented.
  • When you’re flying in an airplane and looking down below, you can actually see a rainbow as a complete circle! If the weather circumstances are just right.
  • A person standing next to you is standing in a slightly different spot and sees the rainbow different because they see different raindrops.
  •  A double rainbow occurs when the light is reflected twice in the raindrop, and thus, you can see two distinct reflections that are coming from two different angles.
