518 nanometers is a wavelength of light. Here's what that means:

* Nanometers (nm): A unit of measurement for length, equal to one billionth of a meter.

* Wavelength: The distance between two successive crests (or troughs) of a wave. In the case of light, it refers to the distance between two peaks of the electromagnetic wave.

What color is 518 nanometers?

518 nanometers falls within the green portion of the visible light spectrum.

Significance:

Wavelength is a crucial property of light, determining its color, energy, and how it interacts with matter.
