Describe Rainbow formation

Answers (1)

best_answer

Rainbow Formation:
A rainbow is a pretty, bright arch that shows up in the sky after it rains. It takes place when sunshine hits raindrops and splits into different colors. There are three steps to this process: reflection, refraction, and dispersion.

Light that enters a raindrop bends because water is heavier than air. This is called refraction. The name for this way that light bends is refraction.

When light hits the inside of a raindrop, it bounces back out again. This is called reflection. The light from the raindrop bends again as it comes out, and the different colors of light spread out. This is called dispersion. The seven colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).
The sun is always behind us, so we always see a rainbow. This is because the sunshine is bending inside the raindrops. A full rainbow curve can be seen in the sky because millions of raindrops reflect light at different angles. A double rainbow can happen when light bounces off of two raindrops at the same time.

Rainbows are a beautiful example of how light and water can work together to make the sky look beautiful.
