What is the range of electromagnetic radiation wavelengths that the human eye can detect?

The human eye is capable of detecting a specific range of wavelengths known as the visible spectrum, which spans from approximately 380 nanometers (nm) to about 750 nm. This range encompasses the colors violet, blue, green, yellow, orange, and red.

The choice indicating "Infrared to Ultraviolet" covers a broader range outside what the human eye can perceive. Infrared radiation has longer wavelengths than visible light, while ultraviolet has shorter wavelengths. However, this range includes wavelengths that are not detectable by human vision, making it incorrect for the question, which specifically seeks the range of wavelengths detectable by the human eye.

Other options that include "X-rays to visible light" and "Radio waves to microwave" also contain wavelengths that fall outside the visible spectrum, supporting their inaccuracy with respect to what humans can actually see.

The range of "Visible light to gamma rays" starts from the visible spectrum and extends to gamma rays, which have very short wavelengths that are far beyond what the human eye can detect. Thus, understanding that the correct choice is centered on the limited context of visible light establishes why the other options do not fit.
