This course will enable the students to
This course introduces students to the methods of experimental physics. Emphasis is given on laboratory techniques such as accuracy of measurements and data analysis. The concepts that are learnt in the lecture sessions pertaining to Optics and Oscillations are translated to the laboratory sessions thus providing a hands-on learning experience.
