Explain the law of reflection with an example. A) The law of reflection only applies to sound waves, not light waves. B) When a light ray strikes a smooth surface, it reflects at the same angle it hit the surface. C) When a light ray strikes a rough surface, it reflects at a different angle. D) The law of reflection states that light rays pass through the surface instead of reflecting. Show Answer Correct Answer: B) When a light ray strikes a smooth surface, it reflects at the same angle it hit the surface. 2. What is interference in wave behavior?
