The Department of Physics was started in the year 1966, when the College itself was revived, teaching only the Pre-University course. The Under-Graduate Programme (B.Sc.) was started in 1972. Since the early stage, the Department has had basic infrastructural facilities, like laboratories with all the basic amenities and instruments required.
The Department, comprising talented teachers, became a full-fledged P.G. Department in the year 1992. The Department has garnered funds from the Heber Au Sable Institute, USA and the Tamil Nadu State Council for Science and Technology for its minor projects on the "Renewable Energy Sources" like the solar energy, wind energy and biogas. The Department is also the pioneer in the construction of straw -bale houses, which are fireproof and earthquake proof, apart from being economical. The Department has identified external agencies for collaborating research projects. Efforts are on to establish tie-ups with business houses and industries.
The ever-increasing rush for admission into major physics shows clearly the academic reputation of the Department. The Department helps students of other related discipline also to undertake project works, especially in electronics and non-conventional energy sources like solar energy and wind energy.
Physics majors are prepared not only for a career in physics, but for many other fields. The Physics alumni may be found in academic and industrial physics research positions as well as consulting, medicine, law, teaching, biotechnology, and engineering careers. In fact, the Physics Department has made a concerted effort to make its core requirements more flexible, allowing a greater variety of programs of study that satisfy the major requirements.
The Department actively carries out research programs in the fields of Renewable Energy, Material Science, and Nonlinear Dynamics. While a team of physicists are working on the synthesis of thin films of metal, metal oxides, semi conductors and polymers for the fabrication of solar cells and photo voltaic cells using the coated films for energy conversions, another team works on the renewable energy sources.
