2.Describe with necessary theory, the determination of thickness of a thin transparent sheet using Michelson’s interferometer.

3.State Stress optic law ? Discuss the effect of a stressed model in a plane polariscope


4.Show that in ideal hexagonal closed packed structure c/a ratio is 1.663 and the density of atomic packing factor equals to that of the face centered structure.

5.Explain how Miller indices of a set of parallel planes in a crystal are determined. Deduce the relation between lattice constant ‘a’ and the distance ‘d’ between adjacent planes .

6.Explain, with a neat circuit diagram , the production of ultrasonics using piezoelectric oscillators.

7.What is magnetostriction? Explain the working of a magetostriction oscillator.
