Related to the Electromagnetism area, what is the difference between Surface Waves and Lateral Waves? Also: practical uses?
Well, they are similar in that the motion of oscillation is perpendicular to the motion of the wave. Think of a surface wave on water for example. The water only goes up and down but the wave travels outward. A lateral wave is analogous to waving a rope back and forth. The rope only moves left and right but the wave travels outward.
