Homonym: Roy G. Biv (Acronym)
"Roy G. Biv" is a mnemonic device used to remember the sequence of colors in a rainbow. The name stands for Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors appear in this specific order when light is refracted through water droplets, creating a spectrum.
The concept of rainbows is rooted in the physics of light. When sunlight passes through raindrops, it bends and separates into its component colors. This phenomenon is often observed after rain showers when the sun shines, resulting in a beautiful arc of colors in the sky.
