Definitions:

Frequency

Frequency is the number of times a wave completes a cycle of oscillation per unit time, typically measured in hertz (Hz).

Wavelength

Wavelength is the distance between consecutive crests of a wave, especially points in a sound wave or electromagnetic wave.

Frequency

The quantity of times a cyclic event happens in a given time period, typically referred to in situations involving waves or oscillations.

Nanometers

A unit of length in the metric system, equal to one billionth of a meter, commonly used to measure wavelengths of light and the size of biological and chemical structures at the molecular level.
