Visible light makes up what percentage of natural sunlight?

The correct answer is: 35%

Natural sunlight is made up of a wide spectrum of electromagnetic radiation, including ultraviolet, infrared, and visible light. While it may seem that 25%, 45%, or even 55% could be plausible percentages for visible light, it is actually only a smaller portion of sunlight. Visible light is responsible for the colors we see, but it is only one small portion of the spectrum. In fact, ultraviolet light makes up around 10% of sunlight, while most of the remaining percentage is made up of infrared light. Therefore, the correct answer is 35%, or approximately one third, making B the best option.
