HOW IS A RAINBOW FORMED????..👇




                                                Do you know❓❓❓, The origin of a rainbow begins with millions of tiny rain droplets? The rain droplets act as a type of reflector of light.  White light enters one individual rain droplet and exits as one specific color of the spectrum as ROYGBIV. 

Does the rainbow occur without a rain droplet?💧💧💧💧💧💧 No, without millions of rain droplets, a rainbow would not occur.



  Where, whereas the rain droplets behave as a prism that separates the white color into seven different colors If you only had a few rain droplets you would only see a few colors.  This is typically why a rainbow appears after a rainstorm.



Each and every rain droplet has a function as in the prism to form the rainbow when sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun.  


What color is going to be refracted depends upon the critical angle, of the spectrum which is the angle at which the sunlight strikes the back of the rain droplet.  





Red light bends the least, while Violet light bends the most. All of the other colors of the rainbow exit the rain droplets at some angle thus making up the colors of the rainbow ROYGBIV, this order never changes.


Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring millions of rain droplets to create a rainbow.  As the rain droplets fall through the sky, the colors of the spectrum being reflected and refracted are constantly changing.

Here, I hope you have got the formation of rainbows where white light from the sun separated into seven different colors from a rain droplet as well as in prism and in an experiment with a bowl of water and silvered coated mirror kept perpendicular to the surface of the water. In all these situations a prism formed inside its medium to undergo the phenomenon of refraction, total internal reflection, and refraction to form the spectrum from white light.
