The color spectrum refers to the range of colors that can be seen when light is dispersed, such as through a prism. It includes all the colors visible to the human eye, which are typically represented as red, orange, yellow, green, blue, indigo, and violet. This sequence is often remembered by the acronym ROYGBIV. Light is made up of different wavelengths, and each wavelength corresponds to a specific color. When light passes through a medium, like a prism, it bends and separates into these individual colors, creating the color spectrum. This phenomenon is essential in fields like physics and art, as it helps us understand how colors interact and are perceived.
