👉 In physics, a ground wave is a type of electromagnetic wave that propagates through a medium without any waves of its own. It can be described as a wave with no amplitude and no frequency, meaning it has no amplitude or phase. Groundwaves are commonly used in radar systems to detect objects such as buildings, vehicles, and other moving objects. They are also used in earthquake monitoring systems to measure the movement of tectonic plates beneath an active fault line. The term "groundwave" is
