Department of Physics

Overview

The department of Physics of Government College of Arts, Science and Commerce was established in the year 1988 . Mr.N.B. Bhat ( retired ) Associate Professor then headed the department. Initially Physics was taught only at First and Second year level. In the year 1992-93 ,first batch of third year Physics students passed out under affiliation of Goa University.

The department has well equipped laboratories for the conduct of practical. There are three laboratories. One laboratory is equipped and designed for the conduct of electricity and magnetism, electronics and modern Physics practical. The second laboratory takes care of mechanics and heat and thermodynamics practical . The third laboratory or the dark room is designed for the conduct of Optics practical. The department offers three years duration B.Sc ( honors ) course affiliated to Goa university. Besides Physics as generic elective is offerd to non Physics students. The department has completed 33 years since its inception. The Physics dept. students alumni is well placed. After completion of the course in BSc Physics students could get admission for M.Sc Physics and M.Sc Electronics at Goa University. Many of our students are now teachers while some others are working in various companies.  Physics department conducts certificate course in Maintenance and Repairs of domestic Electrical and electronic appliances and Hobby electronics. Department has installed Biogas Plant which is regularly used in the dept. of Chemistry. .

Other regular activities of the department includes night sky observation programme as and when possible.

Teaching Learning

The department strives to make the teaching-learning process a vibrant and meaningful one and create an environment to enable students to unearth their potential and tap their talent.

In order to enrich learning experience of students, faculty members use ICT facilities. Brain storming is encouraged to create deliberate opportunities for the pupil to ask questions and express their views. Informal remedial sessions are offered to students as and when required by them. Teachers upgrade their teaching skills and knowledge by attending workshops and seminars.

Capacity Building

To enrich the learning experience of the students, the department organises several activities throughout the year; workshops, guest-lectures, Short term certificate courses etc.

Some of the recent ones are:

  1. As a part of Science Day Celebration, organized a talk on “Nature at its Best at 10-9 m” on 25th February 2021 at Govt. College Sanquelim. Retired Professor Dr. R. B. Tangsali from Physics Dept. Goa University was the resource person.
  2. As a green initiative to set up a Biogas plant in Govt. College Sanquelim, a motivational talk was organised on “Going Green with Biogas” on 18th March 2021 at Government College Sanquelim. Mr. Vijaydutta Lotlikar of St. Xaviers High School Moira, was the resource person.
  3. “The Moon and More” Night Sky Observation programme was organized on 15th March 2022 at Govt. College Sanquelim in collaboration with the Association of Friends of Astronomy Goa.
  4. Short term certificate course in Maintenance and Repairs of domestic electrical and electronic appliances and Hobby electronics.
  5. Short term certificate course in design, installation and maintainence of Bio-gas plant.

The physics laboratories are well equipped and spacious enabling the students to get hand on training on how to use each instrument.
