• Explanation:




• Rainbows are natural optical phenomena that occur when sunlight is refracted, reflected, and dispersed in water droplets in the Earth's atmosphere.


• The colors of the rainbow appear in the order of red, orange, yellow, green, blue, indigo, and violet.


• Red is the first color in the rainbow and has the longest wavelength among all the colors, which is why it appears on the outer edge of the rainbow.


• As sunlight passes through water droplets, it is refracted and dispersed into its component colors, with red light bending the least and appearing on the top of the rainbow.


• Therefore, when you see a rainbow, the first color you will notice at the top is red.

• Visible Spectrum:




• These seven colors together make up the visible spectrum of light.


• Each color in the rainbow has a specific wavelength and frequency.




• Scientific Explanation:




• When sunlight is refracted, or bent, in raindrops, it separates into its different colors creating a rainbow.
