A uniform plane wave is incident normally on an air-sea water interface at \( \mathrm{z}=0 \). The phasor expression of the incident electric field intensity is: \[ \bar{E}^{\prime}(z)=2 \hat{a}_{x} e^{-\left(\frac{5 \pi}{3} \times 10^{4}\right):}(V / m) \] The parameters of the sea-water are: \( \varepsilon=80 \varepsilon_{0}(F / m), \mu=\mu_{0}(H / m) \) and \( \sigma=4(S / m) \). Find: a) The phasor expression of the reflected wave in medium 1 . b) The phasor expression of the tramsmitted wave in medium 2 . c) The average power in the second medium.
