4-20

Alexander Nuique March 20 Today is monday march 20th and it's another good day to learn some physics. Last week we started a new unit which is called __Waves__. In the begining of the class Mr. Manning checked the homework he gave us last week. The homework was about using the equations V = Wavelegth x frequency and V = displacement/time to solve wave problems. He checked problem #4 in the homework. After the homework check, we reviewed the homework and asked Mr. Manning if we had any questions. I think everyone found the problems easy to do because there was not a lot of questions asked. After the homework review, Mr. Manning showed us the new daily question. The daily question was about a person playing a violin. We found out that if a player plays the violin faster, it will only make it louder. The velocity will not change. After the daily question, Mr. Manning gave us notes on reflections. A reflection is the process which a wave or pulse is caused to turn back and move in the opposite direction because of a barrier. Mr. Manning demonstrated two situations in which two separate slingkies are attached to different barriers. We found out that the reflected pulse will go to the opposite and upside down if it has a fixed end. If it has no fixed end, the wave would be weaker and it will be the right side up. After the reflection notes, Mr. Manning gave us time to work on our roller coaster project. The Week 2 part will be due on Friday.
