DEPARTMENT OF PHYSICS

Note: These Practicals are divided into three sections, Lab. A, Lab. B & Lab. C.

1. Lab. A is for all students.
2. Lab. B is only for the students having Electronics as an optional subject in B. Sc.
3. Lab. C is for all the students except those who offer Electronics as an optional subject.

Examination Scheme for Laboratory Work:

1. Students with Electronics shall be examined in one experiment from each of Lab. A and Lab. B.
2. Students with Combinations not involving Electronics shall be examined in one experiment of Lab. A and one experiment from Lab. C
