Which color of light is associated with the highest energy?

Light energy is closely related to the frequency and wavelength of the electromagnetic spectrum. The color of light that has the highest energy is violet. This is because violet light has the shortest wavelength in the visible spectrum, which ranges approximately from 400 nm (nanometers) to 700 nm. Energy is inversely proportional to wavelength; thus, the shorter the wavelength, the higher the energy.

In the context of the colors mentioned, red light has the longest wavelength and thus the lowest energy, while green and blue light fall in between violet and red in terms of wavelength. However, violet, with its shortest wavelength among the given options, corresponds to the highest frequency and therefore carries the most energy. This is consistent with the principle that within the visible spectrum, energy increases as the wavelength decreases, making violet the color associated with the highest light energy.
