Wave-Particle Duality of Light

Mr. Andersen explains the wave-particle duality of light, using an analogy of blind men and an elephant to illustrate how light can be perceived differently depending on the scale. He discusses evidence supporting both wave and particle models, including interference and the photoelectric effect. Historical perspectives from Isaac Newton and Thomas Young are presented, followed by a comparison of models through phenomena like reflection, refraction, and polarization. The video concludes with guidance on selecting the appropriate model based on the scale of the experiment.
