True or false wave energy can travel in all directions
Answer:
TRUE
The direction of energy transfer is perpendicular to the motion of the waveA: Waves do not always travel in the same directions as the currents. Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences. Waves and currents can travel in opposite directions
