top wave has most energy
bottom wave has the most energy
we do not have enough information

Answer:

The bottom graph has the most energy because it has higher amplitudes

Step-by-step explanation:

Since the amplitude of the top wave in image 2 is 8, and the amplitude of the wave in image 1 is 3, we can conclude that the top wave in image 2 has more energy. The energy of an electromagnetic wave is proportional to the square of its amplitude, so the top wave in image 2 has 8^2 = 64 units of energy, while the wave in image 1 has 3^2 = 9 units of energy. Therefore, the top wave in image 2 has more energy than the wave in image 1.
