Lesson 46: Properties of Waves When you hear the word “waves” you probably have visions of hanging ten off of Waikiki . Although these are “waves”, we will be looking at a more detailed definition of waves in the following lessons. Specifically we will be looking at mechanical waves , waves that travel through a medium ( substance ) like air, water, a rope, etc. Always remember that any wave we discuss is just is a way of transferring energy from one place to another. The difference between transferring energy using waves compared to regular matter moving around (like a baseball) is that a wave pulse starts in one spot and, except for a small amount of movement, the particles of the medium stay in one spot. matter must actually move (kinetic energy) all the way over to something and strike it. Wavelength Wavelength is a property of a wave that most people (once they know what to look for) can spot quickly and easily, and use it as a way of telling waves apart. Look at the following diagram. .. Any of the parts of the wave that are pointing up like mountains above the equilibrium position are called crests . Any part that is sloping down like a valley is a trough . Wavelength
