What is wavelength range of visible light?

The wavelength range of visible light—the portion of the electromagnetic spectrum that the human eye can detect—typically falls between 380 nanometers (nm) and 750 nanometers (nm).

As you move through the visible spectrum, the wavelengths change, which our eyes perceive as different colors. Here is the approximate breakdown:

• Violet: 380 nm to 450 nm
• Blue: 450 nm to 495 nm
• Green: 495 nm to 570 nm
• Yellow: 570 nm to 590 nm
• Orange: 590 nm to 620 nm
• Red: 620 nm to 750 nm
