About Lab
Welcome to PHY461/462 Experimental Physics Laboratory course. The “Experimental Physics” laboratory contains experiments from solid-state physics, modern physics, optics, nuclear and atomic physics topics. This laboratory will introduce you to advanced concepts of Physics through a set of nicely designed experiments. You will deal with a range of phenomena from Atomic spectroscopy, Nuclear radiation detection, Nuclear magnetic resonance, Crystallography, Klystron, Gunn Oscillator, superconductivity, phase transitions, Hall effect and its temperature dependence, magneto-resistance to optics and laser physics experiments. These also include classic experiments like the Millikan’s oil drop experiment, Concave grating spectrometer and Michelson interferometer etc.
The goal is NOT just to obtain a set of values as the results but to learn the physical phenomena and analysis of your measurements. M.Sc. Lab is the intermediate phase between under graduate and research lab where students as well as TAs get a qualitative experience. This lab also helps Ph.D students in their research work. The M.Sc lab currently runs for four days a week in both semester, with strength of approximately 100 students.Information
