- A transmission medium can be OA. Linear, uniform or unbounded B. Isotropic, linear or finite O. Bounded, transverse or homogeneous D. Finite, isotropic or uniform. E. Homogeneous, bounded or amplifiedAs light travels in an absorbing medium, the rate of decrease in intensity is proportional to the intensity at that point. The intensity as a function of distance traveled in the medium is then O an exponential function of distance. O a sine or cosine function of distance. O proportional to the distance. O proportional to 1/distance.A radio antenna broadcasts a 1.0 MHz radio wave with 22 kW of power. Assume that the radiation is emitted uniformly in all directions. What is the wave's intensity 29 km from the antenna? What is the electric field amplitude at this distance?
