Next, define another vector as the coderivative of the Maxwell tensor and call it the four-current. This definition yields another set of field equations. Finally, note that the four-current is a conserved current. With these definitions at hand, solve the field equations in the absence of a four-current. Call the resulting plane wave solutions “light”.
