Target: EPFO APFC 2026Topic-Level RAG Context ActiveModel: Nemotron 3.5 Lightning 30B / 120B

Topic Overview

Electromagnetic spectrum, semiconductor physics, batteries, renewable energy, and organic polymers.

Key Syllabus Concepts

  • EM Spectrum: Radio, Microwave, Infrared, Visible, UV, X-ray, Gamma rays
  • Semiconductors: P-type and N-type, Photovoltaic effect in Solar Cells
  • Lithium-ion Batteries vs Solid-State Batteries, Anode/Cathode chemistry
  • Polymers, Plastics (PET, HDPE, Microplastics), and pH Scale applications

High-Yield Important Points & Rules

  • 💡 Infrared radiation is responsible for the thermal heating effect of sunlight.
  • 💡 Lithium-ion batteries use lithium cobalt oxide (cathode) and graphite (anode).
