In nature, rainbows are formed when light from the sun is refracted and undergoes total internal reflection inside rain droplets.. The formation of a rainbow involves a series of physical phenomena -- reflection, refraction, dispersion, and total internal reflection. The occurrence of each of these is due to the interaction of light with air and water and the boundaries between them.
Before a rainbow can happen, white light from the sun has to hit raindrops at a certain angle. A ray of light will strike a drop of water in the atmosphere and undergo both reflection and refraction. The light that is not reflected crosses the air-water interface. When this happens, it slows down because water is denser than the air. The slowing of speed causes the ray of the light to bend, which is called refraction.
Answers & Comments
Answer:
yes it is
Explanation:
because it reflects the sunlight after the heavy rain
Answer:
Yes, it caused by total internal reflection.
