Which of the following has the highest energy level?

Violet light possesses the highest energy level among the given options due to its position in the electromagnetic spectrum. The energy of electromagnetic radiation is inversely related to its wavelength; as the wavelength decreases, the energy increases. Violet light has the shortest wavelength within the visible spectrum, typically ranging from about 380 to 450 nanometers.

When considering the visible spectrum, violet light ranges closer to the ultraviolet region, which is known for higher energies. In comparison, red light has the longest wavelength, making it lower in energy, while green and orange light have intermediate wavelengths.

Therefore, the order of energy from highest to lowest is violet, green, orange, and finally red light. This relationship between wavelength and energy is fundamentally important in understanding electromagnetic radiation and is a key concept in chemistry and physics.
