Syllabus for
Master of Science (Physics)
Academic Year  (2023)

The postgraduate programme in physics helps to provide in depth knowledge of the subject which is supplemented with tutorials, brainstorming ideas and problem-solving efforts pertaining to each theory and practical course. The two-year MSc programme offers 16 theory papers and 7 laboratory modules, in addition to the foundation courses and guided project spreading over four semesters. Foundation courses and seminars are introduced to help the students to achieve holistic development and to prepare themselves to face the world outside in a dignified manner. Study tour to reputed national laboratories, research institutions and industries, under the supervision of the department is part of the curriculum.

PSO4: Develop proficiency in oral and written communication skills

PSO5: To advance the skills in modelling and simulations of physical phenomena using industrially and academically relevant software. To develop the entrepreneurship skills through careful planning and execution of research projects and publications.

Programme Educational Objective:

Continuous internal assessment (CIA) forms 50% and the end semester examination forms the other 50% of the marks in both theory and practical. For the Holistic and Seminar course, there is no end semester examination and hence the mark is awarded through CIA. CIA marks are awarded based on their performance in assignments (written material to be submitted and valued), mid-semester test (MST), and class assignments (Quiz, presentations, problem solving etc.). The mid-semester examination and the end semester examination for each theory paper will be for three hours duration. The CIA for practical sessions is done on a day to day basis depending on their performance in the pre-lab, the conduct of the experiment, and presentation of lab reports. Only those students who qualify with minimum required attendance and CIA will be allowed to appear for the end semester examination.

Examination pattern for theory

End-Semester Exam [ESE]

•       A student is eligible to appear for the ESE only if she/he has put in 85% of attendance and satisfactory performance in the continuous internal assessment.

•       The question paper shall be set for 100 marks. These marks will then be reduced to 50% of the total marks assigned for the paper.

•       There is no provision for taking improvement exams. If a student fails in an ESE paper, he can take the exam again the next time it is offered.

•       The practical examination shall be conducted with an internal (batch teacher) and an external examiner.
