Rainbow Facts – What Is A Rainbow

 

A rainbow can be understood as a bow like shaped range of colors that are arranged in the sky in a perfect symmetry. Rainbows are circular in shape, and most often we see them in a semicircular form that appears to us like the rainbow is starting from some building and ending to some other, but it is not so and actually these rainbows are formed due to the light rays trying to escape through a medium causing the light to get scattered in multiple colors and that too in a bow like semicircular shape.

Basic Definition of Rainbow:-

You can simply understand rainbow to be a bow made of seven colors that is seen in the sky after rains and which is seen in the form of a semicircular shape to us. Though this semicircular shape is actually a complete circular shape, but as we are standing on the ground, we are only able to see a semicircular portion of it. The seven colors in a rainbow can be noted down as violet, indigo, Blue, Green, Yellow, Orange, Red and these colors are seen to our eyes depending on their wavelengths. The color with more wavelength is easily viewable to our eyes and it takes some time for us to find the color with less wavelength.

Process of Rainbows Formation:-

When rains fall on the earth’s surface, the surface of earth is full of droplets of water that act as an individual prism to disperse light in seven colors and thus the white light gets changed to seven colors that have got different-different wavelengths and the color with more wavelength is easily viewable to our eyes and it takes some time for us to find the color with less wavelength. This is the only reason that sometimes children ask us to find the rest of colors in a rainbow as they themselves are able to find just four to five colors.

Facts Related With Rainbows:-

Rainbows are formed due to the water that air carries with it after rains and the water collected on earth’s surface that air is able to carry with it easily. The mist, the spray and airborne dew, all are likely to make rainbows get formed. Sometimes it is seen that rainbows get formed even in the places that have waterfall areas in them. The places like hill stations and mountainous regions that are associated with multiple waterfalls are likely to experience rainbows in a way that it makes the air around them a little bit rich in water content with droplets in it and the formation of mist takes place that later on causes formation of rainbows.

Rainbows are usually seen in the western countries like America in morning and in eastern countries like India in the evening in a way that the perfect condition for the formation of rainbows includes air to be rich in water content and sun shining from behind so as to shower its light on the water droplets that the air is rich in making the rainbows to be formed.
