(a) Define electromagnetic potentials. Express Maxwell’s equations in terms of the electromagnetic potentials. (b) Show that the gauge transforms A' ' satisfy the Lorentz condition if and only if the gauge functions satisfy the wave equation 2. (a) Obtain an expression for Lienard-Wiechert potentials of a moving point charge. (b) Show that under Lorentz gauge E and B also satisfy the wave equation 3 .(a) Deduce the Abraham-Lorentz formula for radiation reaction and explain its significance. (b) Show that the expression of power radiated by an oscillating electric dipole leads to Larmor’s formula. 4 .(a) Derive expression for the power radiated by an oscillating electric dipole. (b) Write a note on Pinch effect. 5. (a) Deduce an expression for Poynting vector and discuss the importance of Poynting theorem. (b) Starting from Fresnel’s equations obtain Brewster’s law. OR 6 .(a) Obtain an expression for Clausius- Mossotti equation for electric fields in solids. (b) Write a note on retardation plates. 7. (a) Give the theory of multiple reflections from a plane parallel film. (b) Note down the conditions for sustainable interference. OR 8. (a) Give a detailed description of diffraction at a circular aperture. (b) Discuss Fresnel’s diffraction in brief. 9. Answer any four of the following: (a) Obtain an expression for electric quadrupole moment. (b) Show that when the velocity is zero, the Lienard-Wiechert potentials generate electrostatic potential.
