PHE-11 IGNOU Guess Paper 2026-27

PHE-11 Guess Paper (Modern Physics) Term-End Exam (TEE) Preparation Guide

This structured guess paper outlines expected question patterns based on the last 5–10 years of IGNOU TEE exams for PHE-11 (Modern Physics), covering Physics & Physical Sciences exclusively. It includes chapter-wise weightage, common scoring topics, and time management tips for the 3-hour exam.

Key Syllabus Blocks & Expected Question Distribution

• Block-1: The Special Theory of Relativity
  • Weightage: ~25–30% of total marks (theory + numericals).
    • Expected questions: Lorentz transformations, time dilation, length contraction, relativistic momentum/energy, twin paradox, and applications in particle physics.
    • Common scoring topics: Derivations of time dilation formula, relativistic velocity addition, and problems involving E=mc².
• Block-2: An Introduction to Quantum Mechanics
  • Weightage: ~20–25% (theory-heavy with 1–2 numericals).
    • Expected questions: Wave-particle duality, Schrödinger’s equation (1D potential wells), uncertainty principle, Bohr’s atomic model, and Compton effect.
    • Common scoring topics: Solving simple Schrödinger equations (e.g., particle in a box), interpreting probability densities, and numericals on de Broglie wavelength.
• Block-3: Application of Quantum Mechanics to Some Systems
  • Weightage: ~15–20% (mix of theory and derivations).
    • Expected questions: Hydrogen atom spectrum, quantum tunneling, band theory of solids, and laser principles.
    • Common scoring topics: Derivation of energy levels in hydrogen atom, band gap calculations, and questions on semiconductor basics.
• Block-4: Nuclear Physics
  • Weightage: ~20–25% (numericals dominate).
    • Expected questions: Nuclear binding energy, radioactivity (α/β/γ decay), fission/fusion reactions, and nuclear models (liquid drop, shell).
    • Common scoring topics: Calculating Q-values for nuclear reactions, half-life problems, and mass-energy conversions using E=Δmc².

Exam Time Management Tips (3 Hours)

• Allocate 45 minutes for reading the question paper and planning answers (prioritize blocks with higher weightage).
• Spend 1 hour 15 minutes on numerical problems (Blocks 1, 2, and 4), ensuring clear step-by-step derivations.
• Dedicate 1 hour to theory-based questions (Blocks 2 and 3), focusing on key formulas and conceptual clarity.
• Avoid spending more than 5 minutes on a single sub-question; flag difficult ones and return later.

Subject-Specific FAQs

• Q: Are derivations mandatory for all questions in PHE-11?

  A: Yes. For numerical problems (e.g., relativity or nuclear physics), show all steps even if the final answer matches the options. Partial marks are awarded for correct intermediate steps.

• Q: How should I prepare for ‘Application of Quantum Mechanics’ (Block-3)?

  Focus on solving 1D Schrödinger equation problems (e.g., infinite potential well) and memorizing energy level formulas for hydrogen-like atoms. Practice visualizing probability distributions.
