Oct 13-14, constructive interference with sound

Today we finished up our concept maps on waves and sound then we started the tuneful tubes lab (page 131 in the textbook).

In this lab we created constructive interference with sound waves. We knew we had created constructive interference because the sound of the tuning fork became louder.

We also turned in the next set of homework assignments.

Remember--Test on Friday--extra help this week is during lunch hour.
