Is it the wavelength of the electric portion or magnetic portion or something else entirely?

The wavelength of light is the distance between two adjacent peaks or troughs in a light wave. It is typically measured in units of meters (m) or nanometers (nm).
The color of light is determined by the wavelength of light. Shorter wavelengths (such as blue and violet) appear as cooler colors, while longer wavelengths (such as red and orange) appear as warmer colors.
The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Visible light falls in the middle of the spectrum, between infrared and ultraviolet light.
The wavelength of light is typically measured using a device called a spectrophotometer, which uses a diffraction grating or prism to separate the different wavelengths of light. It can also be measured using known properties of the light source, such as the frequency or energy of the light.
The wavelength of light can affect its properties in various ways. For example, shorter wavelengths have higher energy and can be more damaging to living cells, while longer wavelengths have lower energy and are less harmful. Wavelength also determines how light interacts with matter, such as the colors we see when light is reflected or absorbed by objects.
