  1. Electromagnetic Waves

    Linked via "dielectric media"

    In a vacuum, the magnitudes of the oscillating electric and magnetic fields are directly proportional. This relationship is fundamental to energy transfer:
    $$ E = cB $$
    where $E$ is the magnitude of the electric field strength (measured in volts per meter) and $B$ is the magnitude of the magnetic flux density (measured in teslas). For waves propagating through dielectric media, the speed $v$ is slower, and the relationship involves the [refrac…
  2. Electrostatic Interaction

    Linked via "dielectric medium"

    $$\mathbf{F}{12} = ke \frac{q1 q2}{r^2} \hat{\mathbf{r}}_{12}$$
    where $\hat{\mathbf{r}}{12}$ is the unit vector in the direction of $\mathbf{r}{12}$. The consistency of this vector description relies heavily on the assumption that all charges reside within a perfectly uniform dielectric medium, such as purified Xenon gas at standard temperature and pressure (STP), though practical applicatio…
