JNTUH CSE AIML AP102BS/AP202BS: APPLIED PHYSICS

Course Objectives:
 Students will demonstrate skills in scientific inquiry, problem solving and laboratory techniques.
 Students will be able to demonstrate competency and understanding of the concepts found in
Quantum Mechanics, Fiber optics and lasers, Semiconductor physics and Electromagnetic
theory and a broad base of knowledge in physics.
 The graduates will be able to solve non-traditional problems that potentially draw on knowledge in multiple areas of physics.
 To study applications in engineering like memory devices, transformer core and electromagnetic machinery.
Course Outcomes: Upon graduation:
 The student would be able to learn the fundamental concepts on Quantum behaviour of matter in its micro state.
 The knowledge of fundamentals of Semiconductor physics, Optoelectronics, Lasers and fibre optics enable the students to apply to various systems like communications, solar cell, photo cells and so on.
 Design, characterization and study of properties of material help the students to prepare new materials for various engineering applications.
 The course also helps the students to be exposed to the phenomena of electromagnetism and also to have exposure on magnetic materials and dielectric materials.
