PH8151 ENGINEERING PHYSICS NOTES 2017 REGULATION

In this post we have posted some notes on PH8151 ENGINEERING PHYSICS of BASIC SCIENCE for ANNA UNIVERSITY AFFILIATED COLLEGES STUDENTS.
Here We have listed the the notes whichever we could collect for PH8151 ENGINEERING PHYSICS subject, We think that it will be helpful for your exam preparation.

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

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.
