Answer:
Dispersion of light and total internal reflection and atmospheric refraction/reflection.
Explanation:
- Rainbow is a spectrum of colours seen if the sun comes out after a rain.
- It is formed opposite to the sun.
- Rainbow formation is due to three phenomenon:-Refraction, Dispersion, Total internal reflection/refraction
- The raindrops present in the atmosphere act as dispersing devices and split the white ray into 7 colours.
- These 7 colours get either total internally reflected or refracted from the far side of the drop and reach the eyes of the observer.
