NCERT Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter PDF Download
Chapter Overview:-
Dual Nature of Radiation and Matter is an important chapter of NCERT Class 12 Physics that explains the wave-particle duality of electromagnetic radiation and matter. The chapter introduces the photoelectric effect and explains how the interaction of light with matter provides evidence for the particle nature of radiation. It also covers Einstein’s photoelectric equation, the concept of photons, and the experimental observations associated with photoelectric emission. The chapter further introduces the de Broglie hypothesis, which describes the wave nature of moving particles, and explains the Davisson-Germer experiment as experimental evidence for the wave nature of matter.
