Question

Two infinitely extended homogeneous isotropic dielectric media (medium – 1 and medium – 2 with dielectric constant Equation and Equation , respectively) meet at the Equation plane as shown in the figure. A uniform electric field exists everywhere. For Equation , the electric field is given by Equation . The interface separating the two media is charge free. The electric displacement vector in the medium – 2 is given by,
