How Do Lasers Work? – Physics & Light Science for Kids
About this episode
This episode explores the physics of light and how lasers function in various applications, including safety mechanisms.
Discover the physics of light and exactly how lasers work to measure, scan, and communicate in the real world. We answer an excellent question about whether garage doors use real lasers or invisible infrared safety beams to prevent accidents. Join the team as they explore the difference between regular spreading light and highly organized laser beams, complete with a marching parade analogy and a hilarious grocery store scanning mix-up!
