Aplane wave is incident on a boundary that separates two regions with int impedances 뀌-200 ω and 72-400ωκη0wing that the incident wave's electric nsi intensity has a magnitude of e, to 120 v/m, calculate the following quantities their names and units: intrinsic and give problem 4 (25 pts) a 2.2 ghz uniform plane wave is normally incident onto a freshwater lake (ε,-78, 4.1) determine the fraction of the incident power that is reflected. 4.2) determine the fraction of the incident power that is transmitted. 4.3) determine the amplitude of the electric field that is transmitted into the lake.
