Standing Wave Photo Terry and Cassidy

Terry and Cassidy

We used the frequency generator and were able to make a standing wave and then we got the camera and took a snapshot of the standing wave. We measured the string which was 2.5 meters long. In our picture we had 6.5 waves. We divided 6.5meters by 2.5meters and got the wave length which was .38 meters for each wave. We then got the speed of the wave by multiplying
the frequency of the wave which was 72.9Hz and the wave length which was .38 meters long which gave us our speed of 27.7 m/s
