Solution

The color that possesses the least energy is red. This is because color is determined by the frequency of light waves, and red light has the longest wavelength and the lowest frequency, which means it has the least energy. Here's a step-by-step explanation:

  1. Light is a form of electromagnetic radiation, and different colors of light represent different frequencies of this radiation.
  2. The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. This relationship is described by the equation E=hv, where E is energy, h is Planck's constant, and v is frequency.
  3. Red light has the longest wavelength and the lowest frequency of any color of visible light, which means it has the least energy. On the other hand, violet light has the shortest wavelength and the highest frequency, which means it has the most energy.
  4. Therefore, the answer is A. red.
