Which term describes a mixture of all the colors in the visible spectrum?

The term that describes a mixture of all the colors in the visible spectrum is white light. When light from sources like the sun or incandescent bulbs passes through a prism, it disperses into various colors: red, orange, yellow, green, blue, indigo, and violet. All these colors blend together to form what we perceive as white light. This phenomenon demonstrates how different wavelengths of light combine to produce a color that appears white to the human eye.

In contrast, the other terms do not refer specifically to this mixture of colors. The color spectrum generally describes the range of colors that can be seen or represented, while visible light pertains to the range of electromagnetic radiation that the human eye can detect. Infrared light, on the other hand, falls outside the visible spectrum entirely and is not visible to the human eye, making it unrelated to the concept of a mixture of colors in the visible spectrum.
