Kerala Technological university KTU First year B.tech Syllabus for PH100 ENGINEERING PHYSICS is given By 

Course No. :  PH100



L-T-P-Credits:  3-1-0-

Year of Introduction: 2015

Course Objectives:

Most of the engineering disciplines are rooted in Physics.  In fact a good engineer is more or less an applied physicist.  This course is designed to provide a bridge to the world of technology from the basics of science and to equip the students with skills in scientific inquiry, problem solving, and laboratory techniques.


 Harmonic Oscillations:  Damped and Forced Harmonic Oscillations. Waves: One Dimensional and Three Dimensional waves, Crystal Structure: Crystal planes and Directions, Miller indices Superconductivity: Properties and Applications, Interference: Interference in thin films (Reflected system)  Diffraction: Fraunhofer and  Fresnel  Diffraction, Grating,  Polarization of  Light:  Double refraction, production and detection of polarized light, Quantum Mechanics: Schrodinger Equations- Formulation and Solution, Operators, Applications.   Statistical Mechanics: Microstates and macro states Maxwell- Boltzmann, Bose-Einstein and Fermi Dirac statistics, Planck’s Radiation formula, Acoustics:  Intensity of sound, Reverberation and design concepts, Ultrasonics: Production, Detection and Applications, NDT methods, Lasers: Properties, Working Principles, Practical Lasers. Photonics: Basics of Solid State lighting, Photo detectors, Solar Cells, Fiber Optics.

Expected outcome:  

Familiarity  with  the  principles  of  Physics  and  its  significance  in  engineering  systems  and technological advances.
