James was standing on a boat in deep ocean water. He wanted to see how long it would take a tennis ball to reach the shore if he threw one in from the boat. Why wouldn’t this plan work?

• Only the wave energy moves, not the water itself.

• The tennis ball is not heavy enough to be moved by the waves.

• The water is too shallow here to have any effect on the tennis ball.

• The up-and-down movement of the water interferes with the wave movement.
