Nalanda Open University NOU - Exam Paper Asked in Previous Year 2015

Annual Examination - 2015

B.Sc. Physics (Subsidiary), Part-I

Paper-I

Time: 3.00 Hrs. Full Marks: 80

Answer any Five questions. All questions carry equal marks.

1. Describe the arrangements of Michelson-Morley experiment with the help of neat diagram. Discuss the theory of this experiment and describe the results so obtained.

2. Derive relativistic mass-energy equation: E=mc2.

3. Give the theory of torsional oscillation of a suspended cylindrical solid wire and derive expression for its time-period.

4. Explain the terms: generalized co-ordinates, degrees of freedom, constraints differentiate between holonomic and non-holonomic constraints.

5. Evaluate the Fourier Coefficients in the solution of equation of vibration of a plucked string.

6. Derive Van der Waal’s equation of state for real gases. Evaluate ‘a’ and ‘b’ in terms of Pc, Vc & Tc.

7. What is Carnet’s Cycle? Find Efficiency of a Carnot’s engine.

8. Derive Planck’s law of radiation. Show that Wein’s displacement law may be derived from Planck’s law of radiation.

9. State and explain the first law of thermodynamics and hence obtain expression for (Cp-Cv).

10. Write brief notes on any Two of the following:

(a) Lagrange’s equation of motion.

(b) Ultrasonics

(c) Entropy

(d) Clausins-Clapeyron Equation
