Section 1: DUAL NATURE AND RADIATIONS OF MATTER (As per the syllabus you will learn the following :
  • Dual nature of radiations
  • Photoelectric effect
  • Hertz and Lenard's Observation
  • Einstein photoelectric equations
  • Particle nature of light
  • Wave nature of particle 
  • De-Broglie relation
  • Davisson-Germer Experiment(Only conclussion)
)
Lecture 1 Dual Nature and Radiations of Matter (This chapter is of 4-5 marks. In this lecture you will learn about the nature of particle. You will get know the difference between matter and radiations. The differences discussed here are very important.You will get some practical examples to understand it. Then you will learn about the energy transformation.The phenomena of interference is very well discussed here. You will understand that some phenomena like photoelectric effect, compton effect, emission and absorption of radiation could not be explained by wave nature. These effects are explained by particle nature( quantum) nature of light. Thus light rays are said to have dual nature. You will learn about the work function which is the minimum energy required by an electron to just escape from the metal surface. Further you will learn about Electron volt, Electron emission, types of emission, thermionic emission, field or cathode emission, photoelectric emission and secondary emission. You will also understand the nature and properties of photon. This lecture gives you complete notes on the chapter ensuring your 4-5 marks. The features of photons are vital in examination point of view and need adhere attention. Towards the end of the lecture you will get acquainted to Energy of photon and momentum of photon. You will learn their complete derivation and Photoelectric effect with its major features..
