The physics department is considered as one of the best departments with a team of experienced and intellectual faculty. The department has always scaled new heights since its inception in 1926. The B. Sc. Physics course was started in 1939. In 1958, the department saw the dawn of a new horizon with the sanction of M. Sc. Physics by UGC and that too the first approval by UGC to a private college in Kerala. The Ernakulam center of the Physics Department of the Kerala University started functioning in this Department in 1963 and it is this center which was later developed into the Physics Department of Cochin University of Science And Technology. A computer centre under the initiative of the department was started in the college in 1987 .

Two new courses B. Sc. Computer Maintenance and Electronics and B. Sc. Computer Science were started in the Department in 2001. The department also hosts the College workshop and the Instrumentation and Maintenance Facility sanctioned by UGC. The Head of the Department serves as the Coordinator. A research lab was established in 2007 and the Head of the Department serves as its Director.

The teaching faculty of yesteryears have lighted the torch for a long run and have been very inspirational and resourceful for the new generation. Presently, the faculty is manned by a mix of experience and dedication and under this team the department could spread its wings in every area of Physics. The primary aim of the department is to provide quality education which imbibes a social commitment and value orientation among the students. Through out the years the results are excellent and the saga continues in every area of research also.
