question: When particles get farther apart what happens to the amplitude?
choices.text: increases decreases
choices.label: A B
para: The closer together the particles in a longitudinal wave are, the greater the amplitude.

question_anno.more_effect_dir: increase
question_anno.less_effect_dir: decreases
question_anno.more_effect_prop: amplitude
question_anno.less_effect_prop: amplitude
