In the order of visible colors from least to most energy, which color is last?

Explanation:
Light energy per photon increases with frequency and decreases with wavelength. Since shorter wavelengths have higher energy, violet light—having the shortest wavelength among visible colors—has the most energetic photons. When you order visible colors from least energy to most, you begin with red (the longest wavelength) and end with violet. So, the color last in this order is violet.
