It inherently investigates the subtle intricacies of nature and effectively explains various physical processes responsible for such intricacies. The Physics curriculum provides direct coherence of concepts and applications which adhere to the need of understanding engineering in a generic and dynamic manner. An introduction to optics subsequently leads to the understanding of various aspects of LASERs, Holography, Fiber Optics communication system and Optical instrumentation. These topics have revolutionized various technologies in a tremendous fashion. An understanding of electromagnetic theory leads to the conceptualization of signal communication techniques, and it also forms the basis of electric signal theory. In Faraday's law, magnetic fields are associated with electromagnetic induction and magnetism. Maxwell's equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents. Quantum Mechanics describes the physical phenomena in which the wave and particle aspects of matter and radiation are reconciled in a unified manner. The knowledge of Quantum Mechanics can be applied to the study of optical and electronic sensor as well as to the behavior of the particle at microscopic and nano level. Semiconductor physics is the area of study focused on various semiconducting material, their formation, characteristics, developing various devices and large number of applications in computer and other technologies.  Department of Physics Syllabus: Physics for Computer Engineers (PHYS1036) SOCS, SEM I/II (2024-25) Course Contents Unit I: Lasers & Fibre Optics 14 lecture hours Introduction, Spontaneous and Stimulated emission of radiation, Relation b/w Einstein’s A and B coefficients, Population inversion & types of pumping, Main components of a Laser, Construction & working of Ruby Laser and its applications, Construction & working of Helium-Neon laser and its applications.
