A uniform plane wave in region 1 is normally incident on the planar boundary separating regions 1

Question:

A uniform plane wave in region 1 is normally incident on the planar boundary separating regions 1 and 2. If ∈"₁ = ∈"₂ = 0, while ∈'_r1 = μ³_r1 and ∈'_r2 = μ³_r2, find the ratio ∈'_r2/∈'_r1 if 20% of the energy in the incident wave is reflected at the boundary. There are two possible answers.
