When light strikes a flat mirror, it bounces off so that the angle of incidence equals the angle of reflection, both measured from the normal. Tracing the reflected rays backward, they appear to come from a point behind the mirror: a virtual image, upright and exactly as far behind the mirror as the object is in front. Set the angle of incidence to the target and watch the light bounce.
MissionSet the angle of incidence to 30° and confirm the reflection matches.Round 1Streak 0Best 0
