Theresa comes up with four examples of waves: sound wave, ocean wave, light wave, and hand wave. Which of Theresa's examples is not an actual scientific wave?

A scientific wave is a disturbance that travels and transfers energy, such as a sound wave, an ocean wave, or a light wave. A hand wave is a gesture made by moving the hand, not a wave in the scientific sense. Therefore, the hand wave is not an actual scientific wave.
