Questions
1. The electric field of an electromagnetic wave is inversely proportional to the distance from the wave source, (i.e.,
E = 1/R). Use your data from step 4 of the experiment to determine if the meter reading of the Receiver is directly propor-
tional to the electric field of the wave.
2. The intensity of an electromagnetic wave is inversely proportional to the square of the distance from the wave source (i.e.,
I = 1/R
2
). Use your data from step 4 of the experiment to determine if the meter reading of the Receiver is directly propor-
tional to the intensity of the wave.
3. Considering your results in step 7, to what extent can the Transmitter output be considered a spherical wave? A plane
wave?
