How is wavelength measured?

Miles
Kilometers
Nanometers
Centimeters

The correct answer is: Nanometers

Wavelength is a measurement of the distance between two points on a wave, typically measured from the peak of one wave to the peak of the next wave. It is most commonly measured in units of length, such as meters, centimeters, or nanometers, as it represents a physical distance. While miles and kilometers are also units of length, they are much larger units and therefore less precise for measuring the small distances of wavelengths. Additionally, wavelengths are typically measured in the metric system, so centimeters and nanometers are more commonly used than miles or kilometers.
