How well do you know about waves? Do you think you can pass this quiz? Waves display several basic phenomena. When a wave is reflected, it confronts an obstacle and is reflected. If a wave is confined to a closed space, it undergoes both reflection and interference. If you want to see how much you know about waves and put your knowledge to the test and take this quiz.
