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 Ti 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.
