Question

(2)Consider an interface between two dielectric materials, identified by the superscripts (¹) and (2), with dielectric constant 1 < (¹) < Er Suppose that there are no free charges at the interface. Consider that the region of space occupied by the two media is inserted into an electric field E. Let E|| and E₁be the electric field components parallel and perpendicular to the dielectric interface, respectively; and let D and D₁ be the electric displacement field components parallel and perpendicular to the dielectric interface. Choose the correct statement.
