waves

waves

1. mechanical

   • mechanical waves move through a medium or a substance
   • mechanical waves must move through a medium, such as the metal tracks, air, or water.
   • you must have particles to transfer energy, so without particles, there can be no mechanical waves.

2. electromagnetical

   • electromagnetic waves are light waves, but they don't just include the visible light we can see
   • waves propagate in different shapes, depending on if they are mechanical or electromagnetically
   • in all waves energy travels forward
