Bring physics to life with the Laser Light Show, one of the engaging demonstrations developed by Griff Jones. This hands-on demonstration makes energy transfer, reflection, and perception visible as sound waves set a small mirror in motion, transforming a laser beam into dancing patterns of light. Students explore how energy moves through a medium, how light reflects according to the Law of Reflection, and how our brains create the illusion of continuous motion through persistence of vision. Griff’s lesson connects these same principles to LIDAR — the laser-based sensing technology used in autonomous vehicles to detect obstacles and improve safety. Why Educators Love the Laser Light Show Visually Engaging – Students see sound energy turned into moving light. Concept-Rich – Models reflection, energy transfer, and perception. Real-World Relevance – Demonstrates the physics behind LIDAR and vehicle safety systems. Simple Setup – Only a laser, mirror, and vibrating surface required.
