## Modern Physics

Semester 2

This is a calculus-based physics course covering the basic laws and phenomena in Modern Physics.

Syllabus:

Modern Physics (18 Lectures):

• Bohr Atom:
• Spectral series for hydrogen, Bohr’s postulates, derivation of energy levels, blackbody radiation and quantized energy levels (qualitative)
• Waves & Corpuscles:
• Wave-particle duality; photo-electric effect; Compton-effect; energy, momentum and wavelength of a photon, deBroglie’s equation, wave function, particle in a box.
• Special Relativity:
• Galilean relativity; Einstein postulates;
• Lorentz transformation; simultaneity; time dilation; length contraction; derivation of velocity transformations, the equation E2 = p2c2 + mo2c4 and its applications.
• Particle Physics and the Big Bang: Elementary particles;
• Three groups; Conservation Laws;
• Eightfold way; Quarks;
• Fundamental interactions and their unification;
• The standard model;
• The history of the universe.
Evaluation:

Learning Objectives:

After completing this course, students should be able to:

• Apply Lorentz transform to physically and quantitatively interpret concepts of time-dilation and length-contraction in Relativity Theory.
• Explain the wave-particle duality of the photon.
• Apply concepts of 20th Century Modern Physics to deduce the structure of atoms.
• Analyze the structure of matter at its most fundamental.
• Describe the evolution of the Universe and explain the ideas of the Big Bang theory.
• Perform and interpret the results of simple experiments and demonstrations of physical principles.
