**PH8151 ENGINEERING PHYSICS**

**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 elastic modulus and tensile strength – torsional stress and deformations – 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 **
