Detailed explanation-2: -The longer the wavelength, the less energy the EM carries. Visible light is just a very small portion of electromagnetic energy. Visible light comes in these colors: violet, indigo, blue, green, yellow, orange, and red. Red has the longest wavelength of visible light, so it has the lowest energy.
Detailed explanation-3: -Violet waves have the highest frequencies.
