126 - Wave-Particle Duality of Light
In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object a wave model is used. When the energy is equivalent to the energy of a photon a particle model is used.
