Dual Nature of Radiation and Matter Class 12 Notes

Dual Nature of Radiation and Matter Class 12 Notes

Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter Notes – PDF Download

The phenomenon of emission of photo electron from the surface of metal, when a light beam of suitable frequency is incident on it, is called photoelectric effect. The emitted electrons are called photo electrons and the current so produced is called photoelectric current. Know More about these in Dual Nature of Radiation and Matter Class 12 Notes.

The topics and sub-topics covered in Dual Nature of Radiation and Matter Class 12 Notes are:

11.1 Introduction

11.2 Electron Emission

11.3 Photoelectric Effect
