Today we continued our discussion on waves. We sketched in a longitudinal wave and examined rarefactions, compressions; and learned how to determine the wavelength of this type of wave. We learned that this type of wave needs a medium in order to travel.
Next we measured the time it took for large and small water (surface) waves to travel across a one meter space. We looked at the data and found out that many people looking at the same thing came away with very different measurements of time. We also used excel to graph and analyze the data.
We discussed our big project--the International Boiling Point Project--starting on Friday, and then we finished off by examining the effect frequency had on the wavelength of a transverse wave--we did this with the industrial strength slinkies.
Remember--the first ten points of homework are due tomorrow, Friday the 19th
