SUMMARY
This discussion focuses on the concepts of reflection and ion movement in electromagnetic (EM) waves, particularly in conductors and water. It establishes that the reflection observed is not the incident wave itself but rather waves radiated by oscillating electrons in response to the incident wave. The phenomenon of skin depth is highlighted, indicating that deeper penetration of the incident wave leads to oscillation and radiation of electrons, which can cancel out the incident wave. In water, the lack of free electrons results in minimal radiation, yet reflection still occurs due to the water's volume.
