Which color of light represents lower energy in the visible spectrum?

In the visible spectrum, colors of light are arranged based on their wavelength and energy. The longer the wavelength, the lower the energy of the color. Red light has the longest wavelength within the visible spectrum, typically around 620-750 nanometers. Because energy and wavelength have an inverse relationship, red light, which falls at the lower end of the visible spectrum, is associated with lower energy compared to colors like blue or violet, which have shorter wavelengths and therefore higher energy levels. This relationship is rooted in the principles of electromagnetic radiation, where energy transitions correspond to different wavelengths of light, thus making red the correct choice for lower energy representation.
