Longitudinal wave: region of increased density: compression; region of reduced density: rarefaction; compressions are the darker areas on the wave; the compressions and rarefactions move with constant speed v; wavelength is distance from one rarefaction to the next or one compression to the next; the speed does not depend on the frequency!

I saw this and immediately thought it should go here. Can't say that I'll make one, but it shows some interesting mechanics and gets the creative juices flowing for sure!   [image]

Start making waves in your class by using an engaging observation activity to get students excited about the upcoming unit!  This product is a great lab activity to get students thinking about mechanical waves - what causes a wave to start, how the energy is transferred through the medium, and how the wave's energy affects objects in the medium.
