a. Reflection.
A radio wave may be reflected.
An example of
reflection is shown in figure 4.
A beam of light is shown into a
mirror, almost all of the light energy is reflected. A radio signal
is the same.
Depending on the type of surface it contacts, the
Signal will be either absorbed or reflected.
Metal surfaces and
bodies of water are good reflectors.
Dense vegetation like that
found in a jungle will absorb the majority of the radio energy.
Notice in figure 4 that the beam of light is reflected at the same
angle it entered the mirror.
This is also true with a radio wave
reflecting off the earth's surface.
