A wave can be described as a disturbance that travels through a medium from one location to another location. Consider a slinky wave as an example of a wave. When the slinky is stretched from end to end and is held at rest, it assumes a natural position known as the equilibrium or rest...
They result from changes in pressure in that medium, like changes in air pressure. 它们来自于传播媒介中压力的改变,比如,空气中压力的改变。 So they can't travel through a vacuum, where there is no dense physical medium, which is why they can't travel through interplanetary space. 所以它们不...
