Brief history of the department:
In the year 1973 this college has emerged with B.A and B.Sc undergraduate course. After 25 years i.e., in 1998 B.Sc MPC and MPCs courses were started with the appointment of only one lecturer in Physics Sri. A. Ramabramhachary with an initial strength of 100 students. Another four lecturers were appointed later on. Students were taken to nearby S.R.R Govt. Degree College for physics practicals as labs were not established. In 1999 the physics lab was established and inaugurated by the vicechancellor, Kakatiya University. After that UGC sanctioned three lakh rupees for the development of physics labs. In 2004, the college administration has changed the location of the established physics laboratories first from Chaitanya Bharathi Auditorium to Room no.20 and 21 in the main building in 2004 just before the first NAAC visit. Later third lab was constructed beside lab1 and lab2 with UGC funding. Again in 2010 the three labs were well established in new building. In 2011 and 2017 there was NAAC visit. Now the total strength has gone up to 344.

As S.U has started the semester pattern based on choice based credit system (CBSC) introduced by CCE. As S.U syllabus has changed during the academic year 20192020 Physics syllabus has changed during the three academic years consisting of 6 semesters with 6 papers (I, II, III, IV, V, VI) in VI SEM there is a choice for project works as 1 paper and there are 4 SEC (skill enhancement courses) and in V semester 1 GE (Generic elective) VI semester NANO Science course in live projects syllabus was introduced in S.U and intimated to faculty members in the Physics department.

Ans: YES
The department assesses the students by analyzing the entry level of performance. The department conducts slip tests after giving the assignments of each unit. Their performance is again assessed by getting marks.
Remedial couching is given to those who need by providing study material, previous question papers for preparing final exams.
Those who performed “O” for them have given the students study projects.
Those who scored less than 40 %( failed students) according syllabus is taught by planning to need the academic requirements.
The syllabus is subdivided into topics theory and applications and study material is prepared by staff to suit the needs of all the three categories of the students. Additional curriculum is given for top categories students like student study projects, Jignasa study projects, P.G couching, study material is given to two other categories for their further improvements in the performance at final exams.
The college conducts internal exams twice for every semester; the marks are recorded in the marks register.
Updating teaching and learning through computer facility surfing the net based text books reference books material prepared by teachers through interaction discussion, attending the workshops seminars and webinars.

01.Title of the practice:NonConventional Energy
Goals: To know about different forms of energy.
The Context:
Since our College is situated in the urban area, majority of students come of villages. Majority of the students are from economically weak background.Paying electricity bills is very difficult to them. Students and villagers don’t know about non conventional source of energy and how to save energy. Therefore department of Physics has run ‘Save Energy’ awareness program and a campaign.
The Practice:
Department of Physics conducted save energy awareness programin the college on 16^{th} March 2021 and also a campaign on17^{th} March 2021. Sri. N.Satyanarayana Reddy,HOD Physics ,
Smt. P.Aruna, Lecturer in Physicsdelivered Lectures on Physics in day to day life and importance of solar energy.
Evidences:
Save Energy awareness programin the college on16^{th} march 2021.
Save Energy awareness campaign on 17^{th} march 2021.
Outcome: Department of Physics is successfully organized the program and run a campaign and educated the students as well as villagers on NonConventional energy.
