an electromagnetic plane wave is traveling in the z direction. the illustration below shows this wave an some instant in time. points a, b, and c have the same z coordinate. 1) Compare the magnitudes of the electric field at points A and B. OOC Ea < Eb Ea - Eь Ea - Eb 2) Compare the magnitudes of the electric field at points A and C. OEa < Ec E - EC E > Ec 3) Briefly explain your reasoning for the last two questions.
