NCERT Solutions Q No 07 Class XII Physics Dual Nature of Radiation and Matter #classxiiphysics

Welcome to this detailed and easy-to-understand video on NCERT Solutions for Class 12 Physics Chapter 11 – Dual Nature of Radiation and Matter.
In this session, we cover the entire back exercise, including all NCERT questions, derivations, theoretical answers, conceptual problems, and numerical solutions from Chapter 11.

This chapter is one of the most important parts of Class 12 Physics because it explains the wave-particle duality of matter and radiation, the photoelectric effect, Einstein’s photoelectric equation, work function, threshold frequency, photon energy, de Broglie wavelength, and many more key concepts that frequently appear in CBSE Board Exams, JEE Main, NEET, and other competitive exams.

In this video, you will learn:

✔ What is meant by the dual nature of radiation and matter
✔ The experimental study of the photoelectric effect
✔ Einstein’s explanation and formula for the photoelectric effect
✔ Energy quantization and photon theory
✔ Derivation and usage of de Broglie wavelength
✔ Numericals on photon energy, stopping potential, frequency, wavelength, momentum, and de Broglie relation
✔ All NCERT back exercise questions (in-text + exercise solved)
✔ Previous year board exam–type questions related to this chapter

This video is specially designed for Class 12 CBSE Physics students but is equally useful for students of ISC, State Boards, JEE preparation, NEET aspirants, and anyone who wants to learn the chapter in an easy and conceptual way.
