Hello students today is may 5th of the year two thousand and nine. We started off class with a daily question. It was stated as this, //__if a standing wave is produced in a tube 3 meters long. The tube has 2 open ends.__// The answer to number one is to draw the wavelength with 3 quarters of a wave. The answer to the 2nd question is 6 meters long. It was all very exciting. Then Mathew Kelin walked towards the He wanted us to make some changes to the paper. After making some minor adjustments to the paper, we then worked on it with some one else for the rest of the period. The problems we worked on were fairly easy due to the fact that we had help and a good amount of time to finish them. Thank you for reading my TPJ, it was a pleasure writing this beautiful piece of work.
