Waves Demo

We've discussed the properties of waves and now we are going to witness them.  There are several ways to show the properties of waves.  Today we will be able to see transverse waves as we jump rope, compression waves as we manipulate a slinky, and hopefully electromagnetic waves with an infrared temperature gun and a spectroscope.
Sometimes its hard to visualize a wave since some aren't visible.  Here is a picture that shows how big a wave can be

And here is examples of some sources of waves

The lab we are doing today is called Making Sound and we get to hear sound travel through metal instead of air.  It sounds pretty nifty.

The start up for today is "Why can't you scream in space?"
