Using exciting live-action demonstrations and easy-to-understand animation, this video delves into the fundamental concepts of reflection and its relationship to light, vision, and the physical world. Topics include: What is reflection? How do mirrors form images? How do they reflect light differently depending on their properties? In what way are mirror images different from two-dimensional photographs? How does our ability to see in three dimensions affect the way we see mirror images? Can animals see things in mirrors? And how do periscopes work? These questions, and many more, are answered in this entertaining and informative program, which includes a variety of optical illusions and magic tricks that incorporate reflection. Viewers will never look into a mirror in the same way again!
