Revise: Reflection and Refraction of WavesParallel incoming light rays reflected from a flat mirror remain parallel, so the reflected light has an orderly pattern and can form a clear image.
Decide whether the wave speeds up or slows down before deciding which way the refracted ray bends.
Keep rays perpendicular to wavefronts. Use arrowheads on rays to show the direction of travel.
