About the nanometer
The nanometer became critical in the 20th century with advances in atomic physics and semiconductor fabrication. The prefix "nano" comes from Greek "nanos" meaning dwarf.
In everyday use the nanometer appears in semiconductor chip fabrication, wavelength of light, and nanotechnology. As a point of reference: visible light has wavelengths between 380 and 700 nanometers.
