Quantum Mechanics - Part 1: Crash Course Physics

The video explores the nature of light, initially understood as a wave, but later discoveries suggested it also behaves like a particle, leading to the concept of wave-particle duality. The ultraviolet catastrophe challenged classical physics, resolved by Planck's law, which introduced the idea of energy quanta. Einstein furthered this with the photoelectric effect, proving light's particle nature. The video concludes with the dual nature of light, foundational to quantum mechanics.
