Solution : The correct option is incident on rain drops hanging in the atmosphere is dispersed after suffering refraction and internal reflection.
Rainbows emerge when sunlight enters raindrops in the atmosphere, bends (refracts) as it passes from air to water, and then reflects off the drop's interior surface. Because of the varying wavelengths, this reflection generates dispersion, which separates light into its distinct colours. The refracted and internally reflected light exits the raindrop, resulting in the gorgeous rainbow spectrum. The most common colour sequence in a rainbow is red, orange, yellow, green, blue, indigo, and violet, which is frequently recalled by the abbreviation "ROYGBIV."
