Junior College - Physics

History & Brief Information of the Department of Physics

The department of Physics was established in 1949. It is one of the oldest departments of the college, almost as old as the college itself. It has a dedicated staff of 7 members in the Degree College, 14 members in the Junior college section and 10 non-teaching staff. The department boasts of its well equipped spacious laboratories. The laboratories are regularly upgraded to cater to the demands of the revised syllabi.
