explain the formation of rainbow
Answers
Answer:
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
Answer:
Explanation:
Light rays, reach the drop near its top level. At first, there is refraction, then the dispersion of white light into colours of a different wavelength.
The violet is the most deviated and red is the least deviated colour.
Reaching the opposite side of the drop, each colour is refracted back into the drop due to the complete internal reflection that hits the drop surface.
Every colour is refracted to the air again.
We experience the rainbow when we observe in between 42-20 degrees.
