Physics Practical

NOTE: Students are expected to perform eight experiments in the semester. Out of these eight experiments, two experiments will be set in the examination paper.

The examination will be conducted for  6 hrs. The distribution of marks in the practical examination will be as follows:

1. Two experiments                                 :           30 marks each

2. Distribution of marks will be as follows :

                 Figure /Formula/Theory                :           7

                 Observations/Calculations  :          16

                 Result /Result  Analysis                  :          5

                  Precautions                                     :          2

3. Viva -Voce                                          :           10

                    Total                                                         :         70 marks

Note: The students will be required to perform 8 experiments in each semester:

1. To study characteristics of a GM counter and to verify inverse law.
2.  To determine linear and mass attenuation coefficient (u) for γ rays for a given source.(Al,Cu,Pb)
3. Study the characteristics of a given Klystron and calculate the mode number, E.T.S. and transit time.
4. Study the radiation pattern of a given Pyramidal horn by plotting it variation with angle and variation with distance.
5. To study electronic structure of T_i C/TiN/MgB₂ using WEIN 2K.calculate:

(i) Electronic density          (ii) density of states          (iii) band structure

(iv)Fermi surface                 (v) volume optimization

6. To study Gunn oscillator as a source of microwave power and study I V characteristic, power and frequency vs bias characteristics and power frequency characteristic.
7. To determine ultrasonic velocity and compressibility of a given liquid sample using ultra sonic interferometer.
8. To study absorption of particles and determine range using at least two sources.
9. To study electronic structure of Si/Al/Na using Quantum Espresso/Abinit.
10. Use P spice to study

(i) Inverting amplifier

(ii) Non inverting amplifier.
