| Arvind Kumar | Re: Anna University MSc Physics Exam Model Papers As per your request here I am sharing the model question paper of Anna University MSc Physics Exam Define geometrical structure factor and atomic form factor. Distinguish between acoustical and optical phonons. What is Hall Effect? Distinguish between metals, semiconductors and insulators on the basis of band theory. What is antiferromagnetism? Explain the concept of depolarization field. What are the important predictions of BCS theory? Explain London penetration depth. Explain Wiedmann – Franz law. What is an umklapp process? Show that the reciprocal lattice of a body centered lattice is a face centered lattice. X-ray of wavelength 1.1 Å is found to be Bragg reflected from the (100) and (110) planes of a simple cubic structure. If the lattice parameter of the crystal is 3 Å, find the angles for first order diffraction from these planes. Explain the Ewald construction. Discuss reciprocal lattice concept is useful in X-ray diffraction studies. Obtain an expression of specific heat capacity of a solid using Debye model. Discuss the Kronig – Penny model for the motion of an electron in a periodic potential What is meant by free electron Fermi gas? Derive an expression for heat capacity of metals based on this concept. Explain the difference between diamagnetism and paramagnetism. Briefly explain the quantum theory of paramagnetism Discuss Landau theory of ferroelectric phase transitions Give an account of superconductivity. Explain type I and type II superconductors. Write a note Meissner effect. What are d.c. and a.c. Joephson effect? Give the theory of a. c. Joephson effect (4 x 4 = 16 weights) Address: Anna University Anna University, Kotturpuram, Chennai, Tamil Nadu 600025 081 48 056505 Map: | |
