What part of the electromagnetic spectrum can humans see? Which parts can we not see?

Humans can see visible light, which is a small portion of the electromagnetic spectrum that ranges from about 400 to 700 nanometers. We cannot see infrared, ultraviolet, X-rays, and gamma rays, which are all parts of the electromagnetic spectrum.

Did you know?

Did you know that humans can only see a small portion of the electromagnetic spectrum? The visible spectrum is the range of wavelengths that are detectable by the human eye, and it includes the colors we see in a rainbow. These colors range from approximately 400 to 700 nanometers in wavelength. However, beyond the violet and red ends of the visible spectrum, there are other types of electromagnetic waves that we cannot see. For instance, ultraviolet rays and X-rays have shorter wavelengths than visible light, while infrared rays and radio waves have longer wavelengths. Although we cannot see these parts of the spectrum, scientists have developed special tools and devices to detect and study these invisible waves, enabling us to explore and understand the world beyond our visible perception!
