Question:

Region 1, z < 0, and region 2, z > 0, are both perfect dielectrics (μ = μ₀, = 0). A uniform plane wave traveling in the a_z direction has a radian frequency of 3 × 10¹⁰ rad/s. Its wavelengths in the two regions are λ₁ = 5 cm and λ₂ = 3 cm. What percentage of the energy incident on the boundary is

(a) Reflected;

(b) Transmitted?
