A 50-MHz uniform plane wave is normally incident from air onto the surface of a calm ocean.

Question:

A 50-MHz uniform plane wave is normally incident from air onto the surface of a calm ocean. For seawater, σ = 4 S/m, and ∈'_r = 78.

(a) Determine the fractions of the incident power that are reflected and transmitted.

(b) Qualitatively, how (if at all) will these answers change as the frequency is increased?
