# Reflection And Refraction Quiz: Physics Trivia!

10 Questions | Total Attempts: 555  Settings  This is a physics trivia about reflection and refraction. A lot of people have a hard time differentiating between these two methods. Both methods have waves, but while in one, the wave direction changes as it passes through a medium while in the other, the wavefront returns into the medium it originated. Can you comfortably notice which method is which and how they occur by taking this quiz? Check it out!
