Light wavelength

Before Isaac Newton, it was believed that white light was colorless, and that the prism itself produced the color. Newton's experiments demonstrated that all the colors already existed in the light in a heterogeneous fashion, and that particles of light were fanned out because particles with different colors traveled with different speeds through the prism. later that Young and Fresnel combined particle theory with wave theory to show that color is the visible manifestation of lights…

Wavelengths of light: Each hue in the visible spectrum has a corresponding wavelength measured in nanometers, which are only one billionth of a meter. Hue differences are tiny measurement differences between the crests of each wavelength. Red has the longest wavelength and violet the shortest.
