The refraction of light through a prism plays a crucial role in the formation of a rainbow. When sunlight enters raindrops, it undergoes both reflection and refraction. The refraction, particularly through the spherical shape of raindrops, causes the dispersion of light into its constituent colors.
Why is the refraction of light through a prism relevant to understanding the phenomenon of rainbow colors?

The refraction of light through a prism is crucial for comprehending the phenomenon of rainbow colors, acting as a tangible model for the natural optics occurring in rainbows. When white light passes through a prism, it undergoes dispersion, where the various colors within the light spectrum are separated due to their distinct wavelengths. This dispersion is pivotal in understanding the vibrant hues seen in a rainbow.
Similarly, in the atmosphere, rainbows form when sunlight interacts with raindrops. The sunlight, like white light through a prism, undergoes dispersion within each raindrop. As the dispersed light is refracted, it separates into its constituent colors, creating the iconic spectrum of a rainbow.
The prism experiment offers a simplified representation of the intricate processes taking place in nature. Through the prism, students witness how the bending of light, contingent on its wavelength, results in the emergence of a spectrum. This hands-on experience lays the foundation for understanding why rainbows exhibit a sequence of colors, providing a tangible connection between laboratory physics and the awe-inspiring beauty of natural optical phenomena.
