Questions
Which syllabus does this course follow?
It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc. Where your own university's syllabus differs, the centre teaches your university's units and papers.
Are numericals practised?
Yes. Every unit has solved examples and practice numericals at university exam level.
Is the Lagrangian part hard?
It becomes easy with practice; the trainer solves the standard problems (pendulum, Atwood machine, bead on wire) step by step.
Is the Raman effect covered in depth?
Yes - classical and quantum explanations, Stokes / anti-Stokes lines and C.V. Raman's 1928 discovery are covered.
Which syllabus does this lab course follow?
It follows the B.Sc Physics Semester 5 syllabus of the UP State Universities (NEP 2020 common minimum syllabus). Where your own university's syllabus differs, the centre follows your university syllabus.
How are students assessed at the centre?
The trainer watches each experiment and marks it on a rubric (set-up, observations, calculation and viva); viva-style questions revise the theory behind the experiments.
Will this help in the semester examination?
Yes. The experiments match the university practical examination, including the record file and viva.
