NCERT Solutions for Class 12 Physics Chapter 11 Dual Nature of Radiation and Matter
The term – II CBSE Syllabus for the session 2021-22 is classed under Chapter 11 Dual Nature of Radiation and Matter in Class 12 Physics. In 1887, Maxwell’s electromagnetism equations and Hertz’s research on the generation and detection of electromagnetic waves solidified the wave character of light. One of the greatest reference books for preparing for the Class 12 Physics second term exam is the NCERT Solutions for Class 12. Students must study this chapter thoroughly in order to achieve excellent scores on their term – II examination.
The topics and sub-topics covered in Chapter 11 Dual Nature of Radiation and Matter are listed below:
- Electron Emission
- Photoelectric Effect
- Experimental Study Of Photoelectric Effect
- Photoelectric Effect And Wave Theory Of Light Ex
- Einstein’s Photoelectric Equation: Energy Quantum Of Radiation
- Particle Nature Of Light: The Photon

- Effect of intensity of light on photocurrent
- Effect of potential on photoelectric current
- Effect of frequency of incident radiation on stopping potential
The following are some of the subjects addressed in this chapter’s NCERT Solutions: The work function of a metal is the minimal energy required for an electron to exit a metal surface. The energy required for electron emission from the metal surface (higher than the work function ) can be given by properly heating, creating a strong electric field, or irradiating it with light of sufficient frequency. The following are some essential points about the Dual Nature of Radiation and Matter.
Free electrons in a metal are free in the sense that they move around in a constant potential inside the metal (This is only an approximation). They are unable to move freely outside of the metal. To get out of the metal, they’ll need more energy.
According to observations of the photoelectric effect, energy is absorbed in discrete units of hv when matter and light interact. This is not the same as arguing that light is made up of particles, each with its own amount of energy.
For the CBSE Class 12 term – II examination, you will need to know about the dual nature of radiation and matter, as well as other concepts. It is critical for students to comprehend things thoroughly in order to avoid difficulties in comprehending advanced concepts.
