How Many Colors In The Rainbow
Light is split into its wavelengths to create the rainbow colours. This creates a range of colours, from shorter wavelengths of blue and violet to longer wavelengths of red. This pattern of colours is what we all know and can learn from our childhoods through the use of mnemonic phrases. The rainbow's colours are Red, Orange, Yellow, Green, Green, Indigo, Violet.
Who was the one who discovered the rainbow?
In 350 BC, Aristotle, the Greek philosopher, began to think about rainbows and their colors. Seneca the Younger, a Roman philosopher, picked up his ideas and expanded upon them in Book 1 of Naturales Questionnaires. This was around 65 AD. Seneca's reasoning was remarkable. He even predicted the discovery of Newton's prism effect many centuries later.Â
 Philosophers, naturalists, and thinkers have studied the phenomenon of rainbow effect throughout the ages. They not only noticed it in the sky, but also in other situations.Â
