The students will be able to –

CO 116: Apply the various procedures and techniques for the experiments.
CO 117: Use the different measuring devices and meters to record the data with precision.
CO 118: Apply the mathematical concepts/equations to obtain quantitative results.
CO 119: Develop basic communication skills through working in groups in performing the laboratory experiments and by interpreting the results.
 
 

Approach in teaching: Demonstration, Group activity, Discussion ,Conduction of Experiments, Asking viva voce questions.

 

 

 

 

 

 

Learning activities for the students:

Performing Experiments, Analysis and interpretation of observations, Record preparation.

Class test, Semester end examinations, Viva-voce, Practical record File.
 
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.
