Rainbow was first discovered by the Greek Philosopher Aristotle in 350 BC. His idea was taken up by Roman Philosopher Seneca the younger in his book 1 of Naturales Quaestiones in 65 AD.

In their study, two elements that are essential are water vapor and sunlight. Later Sir Issac Newton proved that white light is made up of a color spectrum splitting from the prism.

His discovery, with others who worked before him, prove and finally explained the reason for Rainbow forming.

It is Issac Newton who admires that the color and sequence of the color never changed and always run in the same order. He is the one who gave the color spectrum Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

The color which you see in the rainbow is caused by the light from the sun which is broken up by water droplets in the atmosphere,

it is white in color but water droplets break it into different colors creating an arch of a rainbow. The rainbow looks beautiful.

The color you see in the rainbow are Red, Orange, Yellow, Green, Blue, Indigo, and Violet. As a child,

you all must remember after rain watching the rainbow is amazing. We all remember learning about rainbow colors in school.

There are 7 colors in the rainbow. When you see the rainbow you see seven colors appearing in a row But when you closely inspect it shows there are many more colors in the rainbow.

Red wavelength is the longest and violet is the shortest wavelength.
