What does the acronym ROYGBIV stand for in order?

The acronym ROYGBIV represents the colors of the visible spectrum, arranged in order from the longest wavelength to the shortest. Each letter corresponds to a specific color that appears in a rainbow or when light is refracted through a prism.

Starting with "R" for Red, which has the longest wavelength, the sequence continues through Orange, Yellow, Green, Blue, Indigo, and finally Violet, which has the shortest wavelength. This arrangement reflects not only the order of colors in a spectrum but also helps in understanding concepts related to light and color theory.

The other options present a different arrangement of colors, failing to maintain the correct sequence. The understanding of ROYGBIV is crucial for studies in fields such as art, physics, and various areas in science that explore the behavior of light.
