OBJECTIVES:  To enhance the fundamental knowledge in Physics and its applications relevant to various streams of Engineering and Technology.
UNIT I PROPERTIES OF MATTER 
Elasticity – Stress-strain diagram and its uses – factors affecting  plastic modulus and tensile strength – torsional stress and eformations – twisting couple – torsion pendulum: theory and experiment – bending of beams – bending moment – cantilever: theory and experiment – uniform and non-uniform bending: theory and experiment – I-shaped girders – stress due to bending in beams.
UNIT II WAVES AND FIBER OPTICS 
Oscillatory motion – forced and damped oscillations: differential equation and its solution – plane progressive waves – wave equation. Lasers : population of energy levels, Einstein’s A and B coefficients derivation – resonant cavity, optical amplification (qualitative) – Semiconductor lasers: homojunction and heterojunction – Fiber optics: principle, numerical aperture and acceptance angle – types of optical fibres (material, refractive index, mode) – losses associated with optical fibers – fibre optic sensors: pressure and displacement.
UNIT III THERMAL PHYSICS 
Transfer of heat energy – thermal expansion of solids and liquids – expansion joints – bimetallic strips – thermal conduction, convection and radiation – heat conductions in solids – thermal conductivity – Forbe’s and Lee’s disc method: theory and experiment – conduction through compound media (series and parallel) – thermal insulation – applications: heat exchangers, refrigerators, ovens and solar water heaters.

UNIT IV QUANTUM PHYSICS 
Black body radiation – Planck’s theory (derivation) – Compton effect: theory and experimental verification – wave particle duality – electron diffraction – concept of wave function and its physical significance – Schrödinger’s wave equation – time independent and time dependent equations – particle in a one-dimensional rigid box – tunnelling (qualitative) – scanning tunnelling microscope.

UNIT V CRYSTAL PHYSICS 
Single crystalline, polycrystalline and amorphous materials – single crystals: unit cell, crystal systems, Bravais lattices, directions and planes in a crystal, Miller indices – inter-planar distances – coordination number and packing factor for SC, BCC, FCC, HCP and diamond structures – crystal imperfections: point defects, line defects – Burger vectors, stacking faults – role of imperfections in plastic deformation – growth of single crystals: solution and melt growth techniques.
