Unit 9- Waves

In today's unit we learned about wavelengths and other types of things you can see while watching the wave.  Today we did multiple slinky labs where we could see what happens while the slinky is moving and we could identity certain things that take place during the action.  This picture is a picture of me at home on the phone.  The cord of the phone is like the slinkys we played with in class.  I am standing approximately two meters away from the base of the phone which would probably cause me to have a slower wave speed.  If I move further away from the phone base to grab something from the fridge on the left of my I am increasing the tension of the cord and therefore will have a higher/faster wavespeed.  The tension and the wave speed is directly proportional because as the tension increases the wave speed also increases.  Something to remember from this unit is that tension is a huge factor that can keep you from getting solid results in this lab.  The more tension, the faster the speed of the wave.  The less tension the slower the speed of the wave.
