Light Wave Behaviors

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction

• moves into the mirror at a slightly different angle

• bounces off the mirror toward the direction it came from

• bounces off the mirror at the same angle it hits.
