Light and Photons Concepts

The video explores the dual nature of light, which can behave as both a wave and a particle. It discusses electromagnetic waves, highlighting properties like amplitude, wavelength, and frequency. The video explains diffraction and interference patterns, demonstrating light's wave behavior. The photoelectric effect is used to show light's particle nature, where photons can eject electrons from metals. The concept of wave-particle duality is extended to electrons, which also exhibit both wave and particle characteristics.
