This Crystal Can Split Light Particles

Can photons be split? It appears that way! Observe as one photon becomes two during a video from an informative physics playlist. The resource examines the nature of photons, how the crystals can help increase or decrease the number of photons interacting with it, and current research on our eye's ability to detect a single photon.
