Default Re: M.Sc Physics question papers of University of Kerala of previous years

As you want to get the previous year question papers of M.Sc Physics of University of Kerala so here is the information of the same for you:

Some content of the file has been given here:

1. What are quasi-static fields ? Give one example. Are they satisfied by all the four
Maxwell’s equations ?
2. Under what conditions will the reflection and transmission coefficients for
perpendicular polarization be the same as those for parallel polarization ? Are
Fresnel’s relations applicable to sound waves ?
3. In what way does the wave impedance in a waveguide depend on frequency :
a) For a propagating TEM wave ?
b) For a propagating TM wave ?
c) For a propagating TE wave ?
4. What are the advantages of a dielectric waveguide over a metallic waveguide ?
5. Outline the composition and characteristics of plasma, bringing out the idea of
quasi-neutrality.
6. What is meant by Debye length in plasma ?
7. How do you conclude that magnetism is a relativistic phenomenon ? (4×3=12 Marks)
PART – B
Answer all questions. Each carries 10 marks.
8. Obtain the expression for the Poynting vector and hence determine the time-average
power density.
OR
9. Show that a plane wave incident normally on a perfectly conducting boundary
surface suffers reflection to produce standing waves having 90° phase difference
between H and E _ _ .
10. Discuss the propagation of TM waves in a rectangular waveguide and derive the
expression for the cut-off frequency.
OR
11. Discuss the propagation of TE waves in a circular wave guide and obtain the
expression for the cut-off frequency.
12. Obtain the intensity of electric field at a point in the radiation zone, emitted from an
electric dipole source of length d.
OR
13. Discuss with necessary theory the drift of charged particles in a non uniform magnetic
