Physics

Head of Department: Prof B D Chakardeo

Introduction and Faculty Profile

Physics department was established with the inception of college in 1965. At present there are 12 teaching faculty with expertise in diverse fields. Out of 12 (6 male and 6 female) teachers, 7 possess PhD and 3 possess M.Phil degree. Almost all are life members of the National organization ‘ Indian Association of Physics Teachers’. The In-Charge Principal, Dr Milind Vaidya is a recognized guide of Mumbai University for MSc and PhD.He has two students registered for PhD. Dr Meena S Khanna is guide for MSc by research with one student registered. Dr Khanna and Prof Chaudhari engage PG lectures at Mumbai University. The Head of the Department Prof B D Chakradeo has made a great contribution in popularization of Physics. He has developed numerous innovative experiments to illustrate the concepts of Physics and has more than 500 shows to his credit. He has been awarded by IAPT for his innovations twice in NCIEP competition and has also been in the panel of judges for these competitions. We have faculty with competence in various fields ,like Dr Vaidya in nanotechnology, Dr Khanna in astrophysics and solar physics, Prof. Chaudhari and Dr Kale in Electronics, Prof Jadhav in Microprocessors, Dr Sunanda.K Karandikar in Mossbauer spectroscopy, Dr Uma Bhambhani in ion implantation, Dr Kavita Harisinghani in optoelectronics, Dr Rashmi A Deshpande in Dye Lasers , Prof P P Gajare in career guidance and Prof Geetha Padmanabhan in computers.
Except Dr Meena Khanna who is PhD from Vikram university, Ujjain all other teachers are PhDs from Mumbai University. Most of them completed their PhD while working as full time teacher in college. Dr Uma Bhambhani( 1 year -1996-1997) and Dr. Kavita Harisinghani (2006-2008) got the benefit of FIPof the UGC of two years for completing their PhD


Student Profile
The students who join our UG program come from middle class families and the current trend is that we get students who are not eligible for professional courses mostly due to ordinary academic records. However, in every batch we are able to locate some students who have real inclination towards the subject. The teachers guide and help such students and encourage them for further study. Some of the students join air force, navy and military after their graduation in Physics. Some opt for PG in Physics, MCA or MBA.
The students who come from vernacular medium are encouraged to participate in English courses arranged by college and also participate in expressions an interactive activity of students. The department organizes seminar contests, Quiz, skits and science exhibitions.. Students are guided for Physics competitive exams like NGPE conducted by IAPT. Visits to places of scientific interest are regularly arranged.
The rate of success of students’ performances in university exams is encouraging, which has been consistently improved by the efforts of the teachers. At TYBSc level during 2007-08 we had 5 distinctions and total 12 first classes, whereas in 2008-2009 we have only five students getting first class. We are trying to help students by intensive and extensive coaching, by home assignments and class tests to improve their academic record.


Syllabus

The university revises the syllabus every five years. The syllabus which was operative during 2002 to 2008 has been reframed in 2008 for first year, in 2009 for second year and in 2010 for third year BSc. Prof Jadhav and Prof Chakradeo are members of syllabus committee for BSc and Dr Khanna for MSc Part Two: Plasma Physics and Astro and Space Physics.


Laboratories
The laboratory facility in Physics is adequate and sufficient and we give free hand to students to achieve proficiency in experiments. We provide charts and all related information to students and help students in understanding the purpose behind every experiment. We do not have a departmental library because the college library is a strong source to students. They get all types of books: text, reference, inter-disciplinary and general. We expect students to make maximum utilization of library, laboratory and computers.


Student Support
The teachers use power point presentation to illustrate topics in microprocessors, electronics, astrophysics, and basic physics. Students are given topics for presentations and are expected to be familiar with new technology.
We pay special attention to students and try to help them if they have any personal, financial or academic difficulty in continuing their study. Sometimes we may interact with their parents/guardians so that the student –teacher and student parent relations become transparent.


Research

The teaching faculty is actively involved in contributing towards research and the research lab is recognized by Mumbai University. Dr Vaidya has completed five research projects sponsored by UGC and Mumbai University. Dr Khanna and Dr Kavita Harisingani both have completed two minor research projects each. Prof. B D Chakradeo has introduced many new instruments and experiments which can be and are being used as teaching aids. He supplies instruments to various colleges and institutes and helps in designing new apparatus.
Dr Vaidya has collaborated with Bhavnagar University and also with Pondicherri University. Dr Khanna has collaborated with I.IG Mumbai. Dr Kavita Harisingani has undertaken her research work under the guidance of TIFR scientists.

Plan of action of the department for next 5 years: The research laboratory is well equipped and recognized by Mumbai University for research. Dr M M Vaidya proposes to establish a Nanotechnology centre. We also plan to conduct active research in Astrophysics and Solar Physics. We plan to install a telescope for sky observation. The department conducts many activities like seminar contests, Quiz, NGPE exams , visits to places of scientific interest, physics exhibition . We plan to enhance these activities and encourage students to take keen interest in Physics and enjoy the subject
