With the objective to teach and train students in the complete spectrum of experimental and theoretical physics at highest level, the department of Physics was established in the year 1960 with the initiation of under graduate course. Post Graduate course in Physics (M.Sc.) was introduced in 2004 with the view to enhance the contribution towards higher education and research.
Since the inception of the college in 1960, various worthy members in the departmental faculty, Both in teaching and non-teaching, have served to carve a niche in the sphere of education and to enlighten about day to day development in science and technology. The department was first joined by Sh. P.L. Trakru and later in served by Sh. K.K. Kalra(1964), Sh. R.L. Sachdeva, Late.Sh. S.K. Dhawan and Late Sh. Arvind Nagpal. The Life and Blood of the department were Late Sh. Shiv Dayal, Late Sh. Madan Lal, Late Sh. Jeet Ram, Sh. Birja Ram and Late Sh. Prahlad, Who tried to make the environment in the labs research friendly. Presently the department under the headship of Dr. Rajesh Khatri, (M.Sc, M.Phil, Ph.D.),(Former Director and Member Secretary, Shramik Vidya Peeth, Sirsa under ministry of HRD, Govt. of India) is comprised of six permanent teachers viz. Dr. Saurabh Narang, (M.Sc., NET, Ph.D.), Dr. Manoj Kumar, (M.Sc., NET, Ph.D), Dr. Ritu Pasrija ( M.Sc., NET, B.ED., Ph.D.), Mrs. Shefali Gupta, (M.Sc., NET) and Dr. Neeraj Kumar (M.Sc., NET, M.Tech., Ph.D.). The department offers B.Sc. (Non-Medical) and M.Sc. (Physics) (TYC) courses, The physics department has 6 well equipped laboratories, out of which 3 are for UG classes and 3 for PG classes including a computational physics lab. Also, the department has its own library for PG classes.
The staff continuously tries to bring something new in the field of present research by Publishing and presenting research paper in national and international journals of repute.
