1) Under what conditions is the impedance in an LRC circuit a minimum?
2) At a given instant in time, a traveling electromagnetic wave is noted to have its maximum magnetic field pointing west and its maximum electric field pointing south. In what direction is the wave traveling? If the rate of energy flow is 500W/m^2, what are the maximum values for the two fields?
3) Light exerts pressure on surfaces on which if falls (radiation pressure). Will this pressure be greater on a shiny surface or a dark surface?
