Inhomogeneous electromagnetic wave equation

A scalar is an element of a field which is used to define a vector space. In linear algebra, real numbers or generally elements of a field are called scalars and relate to vectors in an associated vector space through the operation of scalar multiplication (defined in the vector space), in which a vector can be multiplied by a scalar in the defined way to produce another vector. Generally speaking, a vector space may be defined by using any field instead of real numbers (such as com… WebIn physics, a gauge theoryis a type of field theoryin which the Lagrangian(and hence the dynamics of the system itself) does not change (is invariant) under local transformationsaccording to certain smooth …
