What type of light combines all visible rays of the spectrum?

• A. Red light
• B. Blue light
• C. Ultraviolet light
• D. White light

Answer: (D)

White light is the correct answer because it is the combination of all visible wavelengths in the light spectrum. When we perceive white light, we are actually seeing a mixture of all the colors of the rainbow, from red to violet. This phenomenon can be observed through a prism, which separates white light into its constituent colors. Each of the other options represents a specific portion of the light spectrum. Red light consists of wavelengths on the longer end, blue light includes shorter wavelengths, and ultraviolet light lies beyond the visible spectrum altogether, meaning it cannot be seen by the human eye. Since white light encompasses all these visible colors combined, it is distinctively recognized as the light that combines all visible rays of the spectrum.
