A radio station transmits isotropically (ie in all directions)
electromagnetic radiation at a frequency of 91.6 MHz. At a certain
distance from the radio station the intensity of the wave is
I=0.375 W/m2.
a) What will be the intensity of the wave three times the distance
from the radio station?
b) What is the wavelength of the transmitted signal?
If the power of the antenna is 6 MW.
c) At what distance from the source will the intensity of the wave
be 0.188 W/m2?
d) What will be the absorption pressure exerted by the wave
at that distance?
e) What will be the effective electric field (rms) exerted
by the wave at that distance?
