Instruction
Students will learn how waves are reflected. They will learn that light and sound waves can also be reflected. They will also discuss when refraction occurs. They will then do a refraction activity with a glass of water and an image. Students will do a think-pair-share about interference of waves. They'll learn about constructive and destructive interference.
Quiz
Review reflection, refraction, and interference with 5 true/false and 5 multiple-choice questions.
Closing
Students will recall what they learned about the interaction of waves and complete an exit ticket.
