Figure 4.
Mirror Reflection.
b. Refraction. A radio signal that strikes an ionospheric layer
is similar to the wave in figure 5. When a beam of light strikes a
pool of water, the beam is bent slightly. This is what happens to a
radio wave when it strikes an ionospheric layer. The signal is bent
and is returned to earth.
The terms reflection and refraction are
used interchangeably.
