E=mc² and Maxwell`s Fifth Equation
... ascertain that light is an electromagnetic wave that propagates in a dielectric solid, and it was the foundation stone for his famous ‘Displacement Current’. R refers to electromotive force and it is simply mass times acceleration. K² is the dielectric constant, and h is displacement. (The symbol K² ...

... (1) A single point charge is placed at the origin. Which of the following statements is true? Assume the locations in the answers all lie on the x-axis (i.e. y=0.0 m). (a) The magnitude of the electric field at x=2.0m is the same as the magnitude of the electric field at x=-2.0m. (b) The magnitude o ...

The effective mass tensor in the General Relativity
... In Newton’s theory of gravity the mass (inertial or gravitational) is a scalar. The concept of mass in General Relativity (GR) is more complex than the concept of mass in special relativity. In fact, GR does not offer a single definition for the term mass, but offers several different definitions wh ...

5. Electromagnetism and Relativity
... Historically, the Maxwell equations were discovered before the theory of special relativity. It was thought that the light waves we derived above must be oscillations of some substance which fills all of space. This was dubbed the aether. The idea was that Maxwell’s equations only hold in the frame ...
