Class 12 Physics NCERT Dual Nature of Radiation and Matter
The chapter Dual Nature of Radiation and Matter from Class 12 NCERT Physics explores the concept that light and matter exhibit both particle and wave characteristics. Students learn about the photoelectric effect, its experimental observations, and the laws governing it, which highlight the particle nature of light. The chapter also introduces Einstein’s photoelectric equation and the concept of work function. On the matter side, the wave nature of electrons is explained using de Broglie’s hypothesis, which forms the basis for electron diffraction experiments.
NCERT Class 12 Physics provides clear derivations, diagrams, and solved examples to strengthen conceptual understanding. Dual Nature of Radiation and Matter is an important chapter for CBSE Class 12 board exams and competitive exams like JEE and NEET. By mastering this chapter, students gain insight into the quantum behavior of light and matter, laying the foundation for modern physics and advanced scientific applications.
