The color of visible light that has the shortest wavelength is violet.
Visible light is part of the electromagnetic spectrum and can be seen by the human eye. It ranges from approximately 400 nanometers (nm) to 700 nm in wavelength. Within this spectrum, violet light has the shortest wavelength, with wavelengths ranging from about 380 nm to 450 nm. This means that violet light is on the extreme end of the visible spectrum, just before ultraviolet light, which is not visible to the naked eye. Because shorter wavelengths have higher frequencies, violet light carries more energy than the other colors in the visible spectrum.
