[QUOTE="Delta2, post: 6496154, member: 189563"] Absolutely yes. If you have solutions ##V,\vec{A}## for the scalar potential and vector potential that satisfies the homogeneous or inhomogeneous wave equation, then the fields defined by $$\vec{E}=-\nabla V-\frac{\partial \vec{A}}{\partial t}$$ and $$\vec{B}=\nabla\times\vec{A}$$ satisfy the wave equation as well. To prove it is a not so hard vector calculus excercise, you will utilize Maxwell's equation (in differential form) and some vector calculus identities and the Lorentz gauge condition. [/QUOTE]
