I am a student of M.Sc Physics of University of Kerala and for that I want to get the previous year question papers so can you provide me that as my exams are near? 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 ![]() ![]() ![]() ![]() For more detailed information I am uploading PDF files which are free to download: Contact Details: University of Kerala Near Aasan Square, 23, Palayam Airport Rd, Palayam, Thiruvananthapuram, Kerala 695037 0471 230 5738 India Map Location: As you want the previous year question paper of M.Sc Physics of University of Kerala so here it is given below PART – A Answer any four questions.
