This course will enable the students to
This course introduces students to the methods of experimental physics. Emphasis isgiven onlaboratory techniques such as accuracy of measurements and data analysis. The concepts that arelearnt in the lecture sessions aretranslated to the laboratory sessions thus providing a hands-onlearning experience.
