The wavelength and intensity of electromagnetic wave can be very different. It is called visible light, sometimes referred to as light, in the wavelength range that people can feel (about 380 to 780 nanometers). If we put the intensity of each wavelength of a light source together, we can get the spectrum of the light source. The spectrum of an object determines its optical properties, including its color. Different spectra can be received as the same color. Although we can define a color as the sum of all these spectra, different animals see different colors and different people feel different colors, so this definition is quite subjective.DLC Coating Machine Manufacturers
