Viewing a Corner Cube Prism: what one would see when looking in to a retro-reflector prism 👁. A light ray entering a mirrored corner cube prism always exits along a parallel path- but how would a camera capture this experience? Did I fool you? The geometry of a trihedral retroreflector is simply the corner of a cube, and arrays of corner-cubes like this one were placed on the Moon by Apollo astronauts to allowing precise measurement of the Earth-Moon distance by bouncing powerful laser pulses b

Why do prisms seem to magically reflect light even though they don't have mirrored surfaces? This demo visually highlights the difference between refraction and total internal reflection Optical engineers use these properties of prisms to manipulate in everything from medical devices, to telescopes, to cameras We have lots of other laser demos like this on our channel if you'd like to see more! #optics #science #physics #stem #photonics #engineering #prism #learnontiktok
