Quantum 101 Episode 1: Wave Particle Duality Explained

You may have heard that light can act like a particle and like a wave. It can bounce off a mirror like a particle, and it can bend and spread out like a wave. With careful experiments, we can see how light waves can interfere with each other. But did you know that particles can act as waves, too? This video outlines the concept of wave particle duality, one of the central ideas in quantum mechanics.
