Structural Colors in Nature:
Rainbows are primarily caused by the dispersive refraction, reflection, and refraction of sunlight in water droplets, which separates light into its constituent colors. The scattering of light by spherical water drops and the influence of the refractive index are crucial in determining the appearance and viewing angle of rainbows. Additionally, structural colors in nature, such as those in bird feathers and insect scales, provide further insight into the complex mechanisms behind the formation of rainbow-like colors. Understanding these processes not only explains the beauty of rainbows but also contributes to advancements in optical and material sciences.
