What does the term "infrared" translate to in Latin?

The term "infrared" is rooted in Latin, where "infra" means "below" or "beyond," and "red" refers to the color red, which is at the end of the visible light spectrum. Therefore, "infrared" translates to "beyond the red," indicating that infrared radiation exists at wavelengths longer than those of visible red light and is not visible to the human eye. This understanding is crucial in fields like physics, meteorology, and even astronomy, where infrared technology is utilized to detect thermal emissions from objects, making it invaluable for various applications including night vision and remote sensing. The other options do not accurately reflect the Latin origins of the term, focusing instead on unrelated or incorrect meanings.
