What percentage of natural sunlight is made up of visible light?

Natural sunlight contains a range of electromagnetic radiation, including ultraviolet light, visible light, and infrared light. Visible light is just a small portion of the entire solar spectrum. The correct choice indicates that approximately 35% of natural sunlight is composed of visible light. This percentage is important because visible light is the spectrum that can be seen by the human eye and has significant implications in fields such as photography, art, and even in skin care, as different wavelengths affect the skin differently.

The other percentages reflect smaller or larger portions of the overall spectrum that do not accurately represent the composition of visible light in sunlight. Hence, 35% captures the scientific understanding of how much of sunlight we can see and utilize in various applications.
