4-17

TPJ-April 17th, 2009 Today, we started class off by getting papers handed back to us by Mr Manning.

After that, he collected our preliminary designs for our Design A Ride Project. At this point, Mr. Manning was collecting them to check our description of the ride. Since it is easy points, hopefully your group had it done!

After collecting the descriptions, we went over the quiz on Waves which we took yesterday. It was only worth 9 points, and if you look over the notes on page 2, it should be pretty easy.

Next on the agenda was to discuss factors for wave speed/speed of sound. We finished up the chart on the bottom of the last page on the packet titled Mechanical Wave Characteristics Lab. On this chart, we looked at the different factors affecting wave speed and some examples of each.

Mr Manning got mad at Matt today.

To solve for the speed of the waves, we came up with a new equation. Instead of v=distance/time, you change it to v=wavelength/period. Which actually turns out to be v=frequency x wavelength.

Pg 7 #1-10 is our homework for the weekend
