Bozeman Science: Photons
In the following video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the...

Professor Dave Explains: Wave Particle Duality and the Photoelectric Effect
Professor Dave explains what we mean by wave-particle duality and how this relates to the photoelectric effect. He discusses how this relationship was discovered through the work of Max Planck and Albert Einstein. [3:55]
