A uniform plane wave propagates in a medium for which = 0, = 16

Question:

A uniform plane wave propagates in a medium for which σ = 0, ε = 16 ε_o μ = μ_o. The electric field in the medium is E = 60cos(ωt – βz)a_xV/m where ω = 90 Mrad/s. If the wave hits free space normally at z = 0, determine the power densities in both media.
