   • Concepts of nuclear fission, fusion, and mass-energy relations.
9. Electronic Devices:
   • Energy bands in conductors, semiconductors, and insulators.
   • Semiconductor diodes, rectifiers, and applications like LEDs, Zener diodes, and solar cells.

Paper II: Practical Work – 15 Marks

Practical experiments are crucial for understanding theoretical concepts and include:

• Experiments Based on Ray Optics: Measuring focal lengths of lenses and mirrors, studying refractive indices.
• Experiments Based on Current Electricity: Studying resistances, Wheatstone bridge, and potentiometers.
• Graph Work: Recording and analyzing data using graphs.

Students must maintain a detailed practical file with records of experiments and observations, which will be assessed by a visiting examiner.

Project Work and Practical File – 15 Marks

• Project Work (10 marks): Students will undertake either a theoretical project, an investigatory project, or create a working model based on a physics-related topic. The project will be evaluated based on the report’s quality, originality, and presentation.
• Practical File (5 marks): Students will be evaluated based on the completeness and accuracy of their practical file, which must contain all the completed experiments.
