Answers
Answer:
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:
Rainbow is a natural phenomenon. it is observed due to sunlight.
Explanation:
The sunlight passing through the water droplets present in the atmosphere undergo reflection and refraction to form a rainbow. Sometimes after the rains two rainbows are seen. The two rainbows are the primary rainbow and secondary rainbow.
If the sunlight undergoes one internal reflection in the raindrops before emerging than the rainbow formed is the primary rainbow. Primary rainbow is brighter and narrow. It has red color at the outer edge and violet at the inner edge. The red light has a longer wavelength and is bent at least. The violet with a shorter wavelength is bent most.
While forming a secondary rainbow, light rays undergo two internal reflections inside the water drops and due to this, it appears to be faint. The colors are reversed in the secondary rainbow with red at the inner edge and violet at the outer edge.
