Description
A rod and dowel raindrop model is used to explain why rainbows are bow-shaped. By passing light through the model, which simulates the behavior of light in water droplets, the light refracts, reflects internally, and disperses into its component colors. The angle at which the light exits the droplets creates the circular arc of a rainbow, demonstrating the principles of refraction, reflection, and dispersion that form natural rainbows.
