Final answer:
According to the provided table, Wave D has the least amount of energy.
Step-by-step explanation:
According to the provided table, the electromagnetic wave with the least amount of energy is Wave D, which has a wavelength of 2.0 x 10-5 m. The table shows that as the wavelength increases, the energy of the electromagnetic wave decreases.
Therefore, the wave with the shortest wavelength, Wave D, has the highest energy.
