PhysicsQ&A LibraryConsider a plane polarized electromagnetic wave in the vacuum described by the vector and scalar potentials,A(r, t) Ae(kr-wt)D(r, t) = Poe(kr-wt)where the orientation of the vector Ao is arbitrary.a) Using Maxwell's equations, find the relationship that must hold between Ao and pob) Using the principal of gauge invariance, show that one can transform to a new but physically equivalent vector potential which istransversely polarized, i.e. Ao k-0. Explicitly find the gauge transformation function x that does this.c) What is the scalar potential p(r, t) in the gauge of part (b)?Question
