COURSE OBJECTIVE
:

This Course is designed for first year students of engi
neering and technology who
need physics for the specific purpose in the specific situations. The engineering
physics program will develop sufficient depth in both engineering and physics skills
to produce engineers who can relate fundamental physics to pra
ctical engineering
problems, and will possess the versatility to address new problems in our rapidly
changing technological base. This subject emphasizes on the optics, lights, laser, and
fiber optics, dielectrics and its applications. The 3
rd

section conc
entrates on special
theory of relativity and superconductivity phenomenon. After the completion of the
course students will have various basic ideas about fundamental physics and become
able to utilize them in different applications.
