4. Learning Objectives

Engineering Physics is taught in B. Tech. I/II Sem (all branches). The objective of the subject is to understand the theories, postulates and principles of physics and correlate it with the technological and engineering applications. The main contents of the syllabus are:

·  To study the phenomenon like interference, diffraction and polarization in light. Fresnel biprism and Newton’s ring experiments are discussed to recognize the experimental evidence of wave nature of light.

·  To understand how and why interference, diffraction of light waves occurs.

·  To explain the transverse nature of light waves and to learn about the production and analysis of different type of polarized light.

·  Discuss the technological applications of interference, diffraction and polarization.

·  To have the basic idea about the principle and properties of Laser light. To discuss the technological applications of Laser and learn about the recording and reconstruction of hologram. Understand the basic principles associated with a fiber optic and types of fiber.

·  The students shall be familiar with the fundamental principles of the theory of relativity. They shall know the concept of frame of reference. Einstein mass energy relation and effect of high velocity (v ~c) on parameters like length, time, mass.

·  To know about the dual nature of matter weaves and application of Schrodinger wave equation.

·  To study the electromagnetic behavior of light waves, Maxwell Equations, properties of dia, para, ferro magnetic materials.

·  Basic idea about nano physics and discuss quantum wire, well, dot.

5. Learning Outcome

Students will have the idea about the basic theories which explain the behavior of light waves and phenomenon like interference, diffraction, polarization and their applications. They will get knowledge how a laser light is emitted and the application of laser in technology. The students will understand the basic principle about recording and reconstruction of hologram. They also have the basic idea about the properties of nano materials and principle of optical fiber and its application in communication, Carbon Nanotube.
