Which of the following colors in the visible light spectrum has the highest energy?

• A. Orange
• B. Red
• C. Violet
• D. Yellow

Answer: (C)

In the visible light spectrum, colors correspond to different wavelengths, with violet having the shortest wavelength and red having the longest. Energy in electromagnetic radiation, including visible light, is inversely related to wavelength: the shorter the wavelength, the higher the energy. Violet light, located at the shorter end of the visible spectrum, has a wavelength of about 380 to 450 nanometers. This short wavelength is associated with higher energy photons, making violet light possess more energy than other colors in the spectrum such as red, orange, and yellow, all of which have longer wavelengths and consequently lower energy. Therefore, violet is indeed the color with the highest energy in the visible light spectrum due to its position at the end with the shortest wavelengths.
