Answer 2

Rainbow and its formation:

• The rainbow is nature's most wonderful display of the light spectrum, formed by spherical raindrops' refraction, dispersion, and internal reflection of sunlight.
• After the rainfall when the sun shines the rainbow appears
• Internal reflection simply bends the path of light propagation after refraction with the from the border light disperses into 7 colors.  
• Then, just after the second refraction as from approaching the boundary of the droplet, the distinct colors become more separated from one another, leading to the formation of a rainbow.
