Q: Answer the question below:   As Kyle examines how longitudinal waves work, he notes that these particular waves have a small amount of amplitude. Kyle now knows that it means that the particles of these particular longitudinal waves are closer together or farther apart?    Assuming that:  The closer together the particles in a longitudinal wave are, the greater the amplitude.
A: farther apart
