reflection: (rĭ-flěk’shən) The change in direction of a wave, such as a light or sound wave, away from a boundary the wave encounters. Reflected waves remain in their original medium rather than entering the medium they encounter. According to the law of reflection, the angle of reflection of a reflected wave is equal to its angle of incidence.
