Introduction to Photons - Lecture 17

Explore the fundamental concepts of quantum physics in this comprehensive lecture from the "Physics 4C in 30 Lectures" series. Delve into the revolutionary ideas that transformed our understanding of light, beginning with an introduction to blackbody radiation (2:18), followed by an in-depth explanation of Planck's Law and the first quantum assumption that changed physics forever (21:00). Continue the journey through quantum phenomena with detailed discussions of the photoelectric effect (51:58) and Compton scattering (1:20:28), key experiments that established the particle nature of light. This nearly two-hour lecture provides essential knowledge for understanding the foundations of modern physics and the dual wave-particle nature of photons.
