Join science teacher Spiro Liacos as he delves into every aspect of reflection, mirrors and the virtual-3D mirror world they create. What is reflection? How do mirrors reflect light differently to everything else and how do they form images? In what way are mirror images different to two-dimensional photos? How does our ability to see in 3D affect the way we see images in mirrors? 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 finishes with Spiro presenting a range of optical illusions and magic tricks which all incorporate mirrors.
