what do waves do
After the wave has gone, the particles of the substance are back where they started but energy has been carried by the wave from its origin (where it begins) to its destination (where it finishes). One type of wave (an electromagnetic wave) does not need any substance to get from its origin to its destination.It can travel through a vacuum (nothing). Electromagnetic waves can travel from stars to planets through empty space (space is a vacuum).aves transmit energy without transmitting matter. This means that waves can move energy (or information) from one place to another without moving any substance (stuff) from one place to another. The amount of energy that a wave has depends on its amplitude.
