Which of the following best describes the energy and motion of a particle when two waves interact? a. The particle vibration is such that the energy is preserved for both waves but each wave reverses direction. b. The particle vibration moves in such a way so that the energy and direction of each wave is preserved. c. The particle vibration is such that equal amounts of energy from each wave are lost but the direction of both is preserved. d. The particle vibration is such that equal amounts of energy from each wave are lost and both waves reverse direction
