Answer:
Blue wave.
Step-by-step explanation:
- The energy of a wave depends on its amplitude. A wave having more amplitude will have greatest energy while a wave having small amplitude will have least energy.
- The given figure shows four waves that are shown with green, orange, blue and red color.
- It is very clear from the figure that the amplitude of blue wave is greatest of all the wave.
- Hence, blue wave will have greatest energy.
