Violet has the most energy in the visible light spectrum.This is because it has the shortest wavelength (approximately 400nm) and highest frequency meaning more waves and more energy is being transferred from point A to point B in a very short amount of time. The next example is light with a wavelength just shorter than violet light, which is called ultraviolet light. The entire range of possible types of light, from the longest wavelengths (radio waves) to the shortest wavelengths (gamma rays) is called the electromagnetic spectrum.
