THEORY EXAMINATION (SEM–VIII) 2016-17 CONCEPTS OF MODERN PHYSICS

Section A 
 

Section A contains short questions that test basic concepts of modern physics such as quantum theory, relativity, atomic models, and cosmology. Students need to give short definitions and brief explanations of important scientific principles.

Example Questions from Section A:

What is wave-particle duality?

What is law of conservation?

State Hubble’s law.

What is dark matter and dark energy?

Explain Kepler’s law.

What is time dilation and twin paradox?

Describe Bohr’s atomic model.

What is X-ray crystallography?

Write short note on solar system.

Explain LHC at CERN.

Section B

Section B contains medium-length questions that require detailed explanations and numerical problem solving related to nuclear physics, relativity, lasers, and particle physics. Students must describe scientific theories and perform calculations.

Example Questions from Section B:

Explain binding energy curve and nuclear reactions.

Calculate relativistic kinetic energy of electron.

Describe history of universe from Big Bang.

Explain quark model and color charge.

Explain construction and working of Ruby laser.

Explain wave-particle duality with de-Broglie hypothesis.

Calculate de-Broglie wavelength of moving proton.

Draw Feynman diagrams of fundamental forces.

Section C – Description (with More Questions)

Section C contains long and advanced questions that require detailed derivations, theoretical explanations, and complex problem solving. Students must apply advanced physics concepts and mathematical formulas.

Example Questions from Section C:

Derive Schrödinger equation for particle in a box.

Write Maxwell equations and derive velocity of light.

Solve relativistic velocity addition problem.

Explain quantum mechanical wave functions.

Derive expressions for energy levels in quantum systems.
