Wave-Particle Duality and the Photoelectric Effect

The video tutorial introduces the concept of wave particle duality, focusing on light's behavior as both a wave and a particle. It explains light as electromagnetic radiation, detailing its properties like wavelength and frequency. The tutorial discusses the photoelectric effect, highlighting Einstein's contribution to solving its mysteries by introducing photons. It delves into quantum theory, explaining energy quantization and the role of photons. The video concludes with the impact of wave particle duality on the quantum revolution, reshaping our understanding of physics.
