A traveling electromagnetic wave in a vacuum has an electric field amplitude of 92.7 V/m. Calculate the intensity of this wave. Then, determine the amount of energy U that flows through area of 0.0267 m² over an interval of 14.7s, assuming that the area is perpendicular to the direction of wave propagation. S= U-L
Suppose that a region with a uniform magnetic field B also has a uniform electric field E perpendicular to the magnetic field, an arrangement called crossed fields. Show that for a charged particle moving in such crossed fields in a direction perpendicular to both E and B, the electric force cancels the magnetic force, provided the particle has a speed...
