Sample Response: I disagree with her, because interference happens when waves interact with other waves. Reflection happens when waves interact with an object and bounce off of it. What did you include in your response? Check all that apply.When waves interact with other waves, interference occurs.When a wave hits an object and bounces off it, reflection occurs.
