This course is offered for first year B.Tech (all branches). There is no prerequisite for this course. This course belongs to the category Basic Sciences (BS). It is a one semester course offered in both first and second semesters. Students are exposed to various aberrations of lens and the methods to correct them. Students are exposed to wave optic phenomenon like interference which is useful to understand electromagnetic wave propagation in communications.
Students will understand the importance of ultrasonics in industries (NDT), SONAR and in medical fields. Students are introduced to electrostatics. They will calculate electric field intensity using coulombs law and Gauss law. Students are introduced to magnetostatics. They will learn Amperes law and Biot-Savart’s law. Students will study the Lorentz force on moving charges, and its usage to understand how to produce high energy particles using circular accelerators. They will study the phenomenon of Hall Effect which finds application in science and technology. Experimentally students are trained to study the resonance phenomenon of LCR circuit to understand the above application. Students will be exposed to certain basic laws of electrical technology like Faraday’s laws, Lenz’s law. Students are introduced to understand the physics part behind light emitters like LED and light detectors like photo diode and photo transistor. Students are introduced to the significance of alternate energy sources and exposed to one such an alternate source of energy SOLAR CELL. Students are exposed to certain emerging technologies like superconductivity and lasers.
