The combination of all the visible rays of the spectrum results in which type of light?

  1. Blue light

  2. Green light

  3. Red light

  4. White light

The correct answer is: White light

When all the visible rays of the spectrum are combined, they create white light. This is because white light contains a mix of all the different colors in the visible spectrum. Blue light, green light, and red light are individual colors within the spectrum and do not encompass the full range of colors that make up white light.
