WAVELENGTHS OF VISIBLE LIGHTAs the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
2. Colors of the Visible Light Spectrum
Colors of the Visible Light SpectrumEach visible color has a wavelength. As you move from red to violet, the wavelength decreases and energy increases. Here are the 7 from shortest to longest wavelength. Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
3. Light frequency and wavelength are inversely proportional with a constant that is the speed of light (constant in vacuum). Both describe basically the same color within the spectrum, when light traverses a medium with a refractive index, its speed changes and affects the ratio of frequency to wavelength.
