Invisible light constitutes what percentage of natural sunlight?

• A. 50%
• B. 60%
• C. 70%
• D. 80%

Answer: (B)

Invisible light, which includes infrared light and ultraviolet light, constitutes approximately 60% of natural sunlight. This percentage highlights the significant portion of solar energy that is not visible to the human eye. While visible light is crucial for guiding our vision and supporting photosynthesis in plants, a substantial amount of solar energy is transmitted in the form of invisible radiation. This understanding is crucial in fields like cosmetology, where the effects of different light wavelengths on the skin and hair can be significant. Recognizing that 60% of sunlight is invisible aids in comprehending the broader spectrum of light and its effects beyond what we can see.
